An extremely rare, if not almost impossible to find Limited Series Gammagarn Version Suea Yant (Yantra Shirt), from 2522 BE, from the Great Buddhist Master Monk of Ayuthaya, Luang Phu Doo Prohmabanyō of Wat Sakae. This Suea Yant belongs to the Gammagarn series which was a small set of Yantra shirts and other amulets of the same edition made for distribution to the larger sponsors of the temple.

The shirt is made from orange prajiad linen cloth as used for monk robes if orange/saffron, and ubiquitously for Pha Yant and Suea Yant if other colors. The Suea Yant is emblazoned with a plethora of Sacred Geometry Spells (Yant), interspersed with images of devotees in prayer, surrounded by Khom Agkhara incantations.

This Suea Yant has hand inscribed Yantra as well as the official gammagarn ink stamps and chakra stamp seal of Luang Phu Doo, and is hence one of the most rare and collectible sacred items of this master, and an extremely desirable item for any devotee of Luang Phu, amulet collector, or aficionado of Sacred Wicha Maha Yant.

Luang Phu Doo made a large number of different amulets during his lifetime, many of them taken from designs which he would beseech from other masters and temples, and others which he would design himself. His very early amulets, especially his Look Om wishing balls, were made from herbal powders with lacquer mixed in (Nuea Pong Kluk Rak), of which very few are to be found anywhere, thereafter, he begin to make them using his Gaew Mani Radtana white crystalline powders, and would release them in every edition in which he released white powder amulets.

It is believed he made over 100 different models of amulets during his lifetime, ranging from Deities such as Brahma and Hanuman, to Guru masters such as Luang Phu Tuad, Lockets, and Buddha Images such as the Pra Somdej. His many talismanic amulets such as this mitmor, and takrut, and other kinds of magical charms such a his Highly Reputed Look Om Powder Balls. LP Doo's Look Om were made using the extra residual Muan Sarn powders used to press different models of amulets, such as the Brahma, LP Tuad, LP Doo 'Roop Muean' Image, and Rachasri Himapant Lion. Luang Phu Doo would then inscribe most Look Om (not all, for later editions found LP Doo older and weaker, and he was not able to inscribe hundreds of amulets every day during his later years). A Takrut would be empowered and inserted with the Look Om as a Heart Mantra spell, to imbue the Look Om with additional powers.

Luang Phu Doo was known to not hand out amulets to his devotees easily, and would only hand out amulets to a devotee when they would show enough faith and effort to practice Meditation, after which he would hand the devotee an amulet, and teach them how to use it for Samadhi Bhavana (practice meditation) and 'Tam Nam Montr' (make Sacred Prayer Water), to heal illnesses with and to increase Auspicious Blessings

One important fact about the sacred Powders of most of Luang Phu Doo's amulets, is that his famous pure white Gaew Mani Radtana powders, release a 'Pratat' (Buddha Dhatu) type crystalline substance, which is considered to be a form of Sacred Relic. The Pratat crystalline sheen, arises through the Sacred Power imbued within the amulet. The crystalline substance grows on the surface in small beads, which are visible when studied close up.

Luang Phu Doo was a great Monk of National Importance, and of Great Purity of practice in his Patipatā, who is believed by many to have attained Arahantship. The amulets were released sometime after 2517 BE at Wat Sakae.

Luang Phu Doo Ordained in 2468 at the age of 21 Years Old in the Uposadha of Wat Sakae in Tambon Tanū, Amper Utai, Pra Nakorn Sri Ayuttaya. His Upachaya Ordaining Officer was Luang Por Glan of Wat Prayatikaram, and Luang Por Dae (Abbot of Wat Sakae), as his Pra Gammawājājarn. His pra Anusawanājarn was Luang Por Chay of Wat Klang Klong Sra Bua. He was given the Ordained Name of 'Prohmabanyo' (Wisdom of Brahma). In his first year of Ordination, Luang Phu Doo studied the Pra Pariyatti Dhamma (Academic Concepts of Dhamma) at Wat Pradoo Song Tam (in those days it was known as 'Wat Pradoo Rong Tam). His teacher was Jao Khun Nueang (Luang Por Rod). Luang Phu Doo also practiced and developed his skill in Vipassana Kammathana practices with Luang Por Glan, and Luang Por Phao (an Adept Apprentice of Luang Por Glan).

Luang Phu also studied the Jatakas and the Dhammapada. Once he had become well studied in all these aspects of practice, he then went on to seek Wicha with other Masters. he travelled to learn under Guru masters of the Province of Supan Buri and of Sra Buri and other Provinces. Luang Phu Doo was known to revere Luang Phu Tuad with Incredible Fervor, but it was also believed by many of Luang Phu Doo's most faithful devotees, that Luang Phu Doo was also a Manifestation of Luang Por Tuad himself, reborn on Earth to make further Merits.

Luang Phu Doo was close friends with many famous masters, but one strange thiing is that, although he never met the Arahant Luang Por Kasem Khemago of the Sussaan Trailaks in Lampang, he always stated himself to be a Devote Admirer of Him and a Student of his Teachings. Luang Por Kasem in turn, was also heard to have recommended his own Devotees to go and obtain of of Luang Phu Doo's Luang Por Tuad Perd Loke amulets.

Luang Phu Doo passed away on 17th January 2533 BE at the age of 85 Years and 8 Months Old, in his 65th year of Ordained Life. He left his devotees Devastated, and his Legacy is contined by his apprentice Masters who follow is footsteps, namely; Luang Ta Ma of Wat Tham Mueang Na, Kroo Ba Bun Chum, and Luang Por Dtiw of Wat Mani Chonlakhant.
