Mae Phosop: The Thai Rice Goddess, Her Rites and Variants

Mae Phosop (แม่โพสพ, also written Phosop or Phaisop) is the rice goddess of Thai folk belief, a figure that English Wikipedia describes as closer to ancient Thai folklore than to a structured, mainstream religion [2]. Thai farmers address her through rice-soul ceremonies (ทำขวัญข้าว, tham khwan khao) held at set points in the growing season, and the details differ from region to region [1], [8]. The annual Royal Ploughing Ceremony is a separate state rite that marks the start of the rice season [3], [4].

Key facts

Who Is Mae Phosop? Names and Titles in Thai Belief

Thai Wikipedia introduces Phosop as a rice deity in Thai belief and lists her names in other languages [1]. These include Phosi, Khosok (โคสก) in the Northern and Isan dialects, Ya Khwan Khao in Tai Lue, and Mak Hiang in Pattani Malay [1]. English Wikipedia adds the title Mae Khwan Khao, glossed "Mother of Rice Prosperity" [2].

The oldest written mentions are literary and legal. The Ayutthaya-era poem Khlong Thawathotsamat names the deity "Phra Phaisop" in several spellings, and the figure also appears in the Law of the Three Seals, compiled in the early Rattanakosin period under King Rama I [1]. The same article says she was originally female and that a male counterpart with a fish as a mount appeared later [1].

Scholars disagree about her origin. The historian Sujit Wongthes is quoted as saying the original name was Mae Khao ("Mother Rice"), a rice ancestor spirit in the native Phi religion, renamed when Thai speakers took on Indian language and religion [1]. Later belief linked her to Lakshmi, to a consort of Indra named Sawadevi, or to Kuvera (Vessavana), and Nipatporn Pengkaew is cited as deriving Phaisop and Phosop from Vaisravana [1].

Origins in Tai Folk Religion, the Khwan and Legends

Thai Wikipedia says Phosop belongs to the traditional belief of Tai-language peoples, built from the veneration of female spirits, belief in the khwan and a long-standing agricultural society [1]. English Wikipedia describes the Tai folk religion, Satsana Phi (ศาสนาผี), as the ancient native religion of the Tai people, based primarily on Phi, Khwan and ancestors [12]. It defines the khwan as an element of vitality and longevity present in living things [12].

Folk belief was handed down orally until it was recorded, and Phraya Anuman Rajadhon (1888–1969) was the first Thai scholar to study local folklore seriously [17]. Buddhism is followed by around 92.5% of Thais as of 2021 [16], and Thai Wikipedia says that Thais who adopted Buddhism kept older beliefs alongside it: rice is offered to monks, dedicated to ancestors, and used to pay respects to Phosop out of gratitude [1].

Legends told about her

A southern Thai religious manuscript, the Nai Chai Chanrotphai edition of "Lok Patisandhi and Tamnan Sang Lok", calls her Nang Phosali, an invisible being who entered the rice plant [1]. In it she leaves in distress when people credit a bodhisattva rather than her, hands seven rice seeds to the creatures sent to find her, and the first rice-soul ceremony follows when a fish is cut open and a rice khwan is found inside [1]. A Phatthalung folk tale has a rice goddess, disguised as an old woman with seeds, taken in by a poor couple after villagers refuse her [1].

Scholarship records similar stories. A 2016 study of Phetchaburi farmers describes a deity who came down to help humans and withdrew into the forest because people did not recognise her kindness [7]. A 2023 article notes a southern legend about a conflict between Mae Phosop and a bodhisattva [9].

How Do Thai Farmers Perform the Rice-Soul Ceremony (ทำขวัญข้าว)?

Thai Wikipedia describes two ceremonies in a rice season, addressed to Phosop as a delicate young woman [1]. The first is held when the rice flowers or "becomes pregnant", comparing her with a pregnant woman who craves foods [1]. The second follows threshing and storage in the granary and is a calling of the khwan, because she is described as sensitive and easily startled [1].

A study of fifteen farming families in Mueang and Sai Ngam districts, Kamphaeng Phet, found three stages of the rice cycle: the forming of the ears, when farmers speak of the "pregnant" Mae Phosop; harvest and storage in the barn; and milling the stored rice for eating [8]. A ceremony of calling the rice spirit (เรียกขวัญ) is held when the ears form, with sour foods of the kind a pregnant woman is said to like, and a ceremony of receiving the spirit (รับขวัญ) at harvest with whatever food and sweets are available [8]. The authors note that details vary from village to village [8].

A worked example from Pathum Thani

Thai Wikipedia gives one detailed local procedure, from Pathum Thani province [1]. The preparation includes a chaleo (เฉลว), a three-coloured flag, perfumed powder, perfumed oil, a comb and a mirror [1]. Women carry food and offerings in a basket to a small shrine at the head of the field bund [1].

The sequence is: light three incense sticks, recite the standard Buddhist homage three times, say the formulas honouring the Buddha, the Dhamma and the Sangha, and then speak the words that call Phosop to the offerings [1]. The performer rubs perfumed oil on rice leaves, combs them, sprinkles powder over the offerings, calls out three times and walks away without looking back, because Phosop is said to be shy and would not accept the offerings if watched [1].

Regional Variants of Mae Phosop Rites

Thai Wikipedia says each locality has its own rites and customs for the ceremony [1]. The examples below are samples, not a complete map.

Central Thailand

The Pathum Thani procedure and the Kamphaeng Phet study both belong to the central region [1], [8]. In Phetchaburi, a 2016 study by Withun Khumhom found that rituals once held by communities had become personal and had been adapted to individual commercial interests [7]. The author links local belief in a good harvest to Mae Phosop's khwan and to auspicious timing for farming [7].

The South

For Phatthalung, Thai Wikipedia lists offerings of savoury and sweet food, a fish with head and tail, puffed rice, flowers, betel, a ring, money, lustral water, sacred thread and a banana-leaf offering vessel [1]. The Triple Gem is honoured, deities are invited, and Phosop is saluted before the rice-soul recitation is chanted [1].

In Ban Phithen, Pattani, villagers tie and honour the harvested rice in a rice house and set on it a brass water vessel shaped like a duck until the water dries by itself, once a year [1]. A 2023 article on southern rice culture lists a rice-khwan ceremony, rice tying, in some localities a procession of "sangked" rice before planting, and a ceremony called La Sang at the end of the farming season [9]. Thai Wikipedia adds that the honouring has declined, especially among Thai citizens of Malay descent who have given it up because it conflicts with Islamic teaching [1].

The Northeast and the North

A 2025 article in the social science journal of Rajabhat Maha Sarakham University describes Boon Bok Fah, an Isan ritual practised since ancient times and held on the third waxing day of the third lunar month [10]. The author reports the belief that on this day the heavens open the gate for rain, after which farmers prepare for planting in the belief that the fields will be fertile through Mae Phosop's grace; the study, based on interviews with 35 participants, examines a dance performance for her within the annual worship ceremony in Maha Sarakham [10].

For the North, the names Khosok and Ya Khwan Khao show that the figure is known there [1]. A 2021 article by Chiang Mai University researchers says the tham khwan khao ritual rests on the belief that a sacred female spirit, Mae Phosop, looks after the rice and makes it grow abundantly, and that the ritual has faded as farming adopted new technology, though it names no specific northern province [6].

Images of Mae Phosop: Plaques, Murals, Logos and Shrines

Thai Wikipedia traces her earliest images to a standing woman holding plants [1]. A stone chawet (เจว็ด) of Ayutthaya art shows a goddess holding a spray of plants, and a terracotta chawet found in the old palace at Ayutthaya shows a goddess standing on a turtle, one raised arm now broken; the article says the second is presumed to be Phosop, and both are in Chantharakasem National Museum [1]. A mural in Phra Thinang Phaisan Thaksin in the Grand Palace shows her standing with ears of rice among other deities [1].

Recent images, Thai Wikipedia says, are modelled on Nang Kwak, another native figure: a young woman seated in the phap phiap posture, holding an ear of rice in her right hand and a bag of rice in her left [1]. English Wikipedia describes the usual picture as a woman in full jewellery and a red or green dress, with a sheaf on her right shoulder, and notes that a young village woman may dress as Phosop at harvest festivals [2]. The Rice Department of the Ministry of Agriculture and Cooperatives uses her figure in its logo [2].

In Bangkok, English Wikipedia names shrines at Wat Siri Wattanaram in Taling Chan, where she is enshrined with Nang Kwak and Phra Mae Thorani, and in Soi Lat Phrao 1 [2].

What Is the Royal Ploughing Ceremony?

The Royal Ploughing Ceremony (พระราชพิธีจรดพระนังคัลแรกนาขวัญ, Phra Ratcha Phithi Charot Phra Nangkhan Raek Na Khwan) is an ancient royal rite held in several Asian countries to mark the traditional start of the rice-growing season [3]. In Thailand the court ceremony has two parts in sequence: Phuetcha Mongkhon, a Buddhist rite set up in the reign of King Mongkut (Rama IV), and the Brahmin Charot Phra Nangkhan Raek Na Khwan, traced by Thai Wikipedia to Sukhothai [4]. The Thailand Foundation says the two have been combined since Rama IV [5].

Day one and day two

On the first day the Buddhist rite is held in the ordination hall of Wat Phra Si Rattana Satsadaram in the Grand Palace, with monks chanting over seeds such as paddy rice, sticky rice, sorghum, maize, beans and sesame, with the stated aim that the seeds be free of disease and grow well [4]. The monarch confers the ring and goad of the Phraya Raek Na role on the Permanent Secretary of the Ministry of Agriculture and Cooperatives and anoints the female attendants (thepi) [4].

The ploughing follows the next morning at Sanam Luang, an open field of 74.5 rai in front of Wat Phra Kaew and the Grand Palace [4], [14]. The Phraya Raek Na honours the images in the Brahmin hall, picks a cloth after making a vow, anoints the oxen and plough, ploughs three rounds clockwise and three more while sowing rice seed, then three rounds to cover it [4]. Brahmins then offer seven kinds of food to the oxen, and the royal astrologer gives a forecast according to what they choose: in Thai Wikipedia's table, rice or maize points to abundant grain and fruit, and water or grass to a reasonable water supply [4].

Roles, seeds and dates

The Thailand Foundation says the Phraya Raek Na (the "Lord of the First Plough") is today the Permanent Secretary, who prays, picks the cloth and sows the royal rice seeds [5]. Two oxen are chosen, and the blessed seeds are mainly rice plus 40 other kinds, packed in white cloth sachets that farmers may collect and sow in their own fields [5]. The date is set each year by an astrologer or Brahmin priest and is usually in May [3], [5]; Thai Wikipedia reproduces a ten-year list of dates announced by the Royal Household Bureau, giving 13 May 2026 (BE 2569) [4].

History of the ceremony

Thai Wikipedia says the king presided but did not plough himself in Sukhothai [4]. The full ceremony ran until 1936 (BE 2479), the Buddhist part resumed in 1947, and the two-part form returned in 1960 (BE 2503) [4]. The Thailand Foundation separately says it was interrupted for over three decades and revived in 1960 [5].

Is the ceremony a Mae Phosop ritual?

The accounts of the ceremony in Thai Wikipedia and from the Thailand Foundation do not mention Mae Phosop [4], [5]. English Wikipedia's article on her mentions the ceremony only as an annual event at which people collect seeds from the furrows [2]. English Wikipedia's article on the rite traces it to the Ramayana, where the baby Sita appears from the earth when King Janaka of Videha ploughs in a royal ceremony, and says a sixth-century Balarama statue holding a plough from Angkor Borei is considered the earliest evidence relevant to the Cambodian form [3].

How the Rites Have Changed

English Wikipedia says paying homage to Phosop has become increasingly rare among rice farmers in modern Thailand, and that Queen Mother Sirikit gave royal patronage to the custom in August 2008 [2]. The Phetchaburi study reports rituals that were once communal becoming personal and, in some cases, commercial [7], and the Chiang Mai University authors place the ritual's decline alongside changes in farming technology [6].

Rice remains central to the economy: the value of all Thai rice traded in 2017 was 174.5 billion baht, about 12.9% of farm production, and Thailand has the fifth-largest area under rice in the world [15]. A Thai PBS programme page of 16 October 2018 says farmers' rice rituals from transplanting to harvest rest on the belief that Mae Phosop resides with the rice [11].

How Mae Phosop Compares with Other Rice Goddesses

English Wikipedia lists parallel figures in Southeast Asia [2]. Dewi Sri is the Javanese, Sundanese and Balinese goddess of rice and fertility, still widely worshipped on Java, Bali and Lombok; her name comes from Sanskrit sri, which the article glosses as wealth, prosperity, health, beauty and good fortune and notes is another name of Lakshmi [13]. In Bali she has special shrines in the rice fields [13].

The Phosop article says the Cham rice goddess Po Ino Nogar has attributes and rites similar to the Thai and Lao goddess [2]. In Laos, where she is called Nang Khosop, a Wat Si Saket manuscript tells of a young man who caught a golden fish and freed it in return for a treasure, Nang Khosop, the maiden who was the soul of the rice; a hermit later cut her into pieces that became the different kinds of rice [2].
