Yant Mongkut Phra Phutthachao (Crown of the Buddha Mandala)
A circular and square interlocking mandala encoding the 'Itipiso Ruen Tia' (Crown of the Buddha) stanza historically associated with Luang Pu Iam of Wat Nang Nong (Rama V era) and Luang Phor Guay of Wat Kositaram.
Features a central 3×3 or 4×4 square framed by four semicircular lotus petals and concentric circular rings inscribed with the 32 syllables of the Mongkut Phra Phutthachao chant, topped by a tiered royal spire (Mongkut).
Recorded in Bangkok-era monastic manuscripts as the verse offered by Luang Pu Iam Suvannasaro of Wat Nang Nong to King Chulalongkorn (Rama V) before his BE 2440 (1897 CE) royal tour of Europe, and later stamped onto the reverse of Luang Phor Guay's famous BE 2521 Third Issue medallion at Wat Kositaram.
