Yant KroPetch"  = Diamond Armor Yant

Yant Kropetch itself is a most important Yant, but when writing the Yant on a paper in full text it's will become a most efficacious Katha (mantra).   

Yant Kropetch derived from the vertical reading of I-TI-PI-SO TON HONG (Please see the tabular cells diagram below).

I-TI-PI-SO TON HONG is the first stanza specifically praising Lord Buddha.

LP Parn of Wat BangNomkho, Ayuthaya province, found the Katha in B.E. 2458 while he was making a pilgrimage to Suphanburi province.

Shortly before he found this great Katha, he was meditating and a Yana (supernatural sense) had emerged from his smadhi that there was a very important plate buried in the main stupa of Wat PhraSriRatanaMahaDhat, Suphanburi province, waiting for him to fetch.

Not long after that he reached the stupa and found the old ancient silver plate inscribed the Katha script of Yant Kropetch.

The plate describes that one who found this Katha is so great because it's the heaven wish to destine the great one to get it.

The plate also describes that one who recites this Katha everyday he will be covered with Diamond Armor and safe from all dangers, and he will never be destroyed by the enemy. Moreover, the enemy will be destroyed by some strange phenomena because of the reflective result from the magic Diamond Armor !! 

In any year that had the auspicious Sao Ha day (Saturday, the fifth day of waxing moon period, lunar month), LP Parn would perform a very special ritual, consecrating and embedding Yant Kropetch into his thousands disciples gathering in Wat BangNomkho.

LP Parn would write the Katha on a blackboard and tell everybody to choose one letter of the script NA-MO-BUDH-DHA-YA (five Buddha names). Then he would stand behind the blackboard and recite the Katha to push the script flashing onto all disciples.

If a recipient has a good meditative property, a letter he chose would embed on his forehead for life long. Amazingly, it often occured that when a recipient died and was brought to cremate, the script would clearly appear on the forehead skull remnant.
