Yant Phra Sivali — Hua Jai Na-Cha-Li-Ti (Four-Corner Alms Bowl Matrix)
A four-petaled lotus or diamond seal housing the four syllables 'Na Cha Li Ti'—the canonical Heart of Arahant Sivali—found on virtually every Phra Sivali, Phra Sangkachai, and merchant amulet in Thailand.
Arranged as four interlocking lotus petals or a four-cornered diamond enclosing 'Na', 'Cha', 'Li', 'Ti', frequently surrounding a central alms bowl (Bat), fan (Talapat), or walking staff of the Elder Sivali.
Derived from the Anguttara Nikaya Etadagga-vagga (AN 1.204), where the Buddha declares Phra Sivali foremost among bhikkhus who receive alms requisites (Labhinam). Luang Phor Guay of Wat Kositaram and Luang Pu Toh of Wat Pradoo Chimplee inscribed 'Na Cha Li Ti' extensively on Phra Sivali and Phra Pidta Plod Nee reverses.
