LP Sodh (B.E.2427~2502) attained Damagaya in B.E.2459, and since then was teaching the knowledge or Dhamma to his disciples until he died in B.E.2502. Dhamagaya is a very supernatural Dhamma, even its basic and intermediate level could bring about comprehensive miracles, such as creating any weather in the area at wish, healing illnesses that the modern physician cannot cure, detecting and finding the hidden or lost objects, foreseeing the future or going back to the past to examine Karma etc. Dhamagaya is so miraculous that all black magic will surrender to it. So one who attains Dhamagaya comes closer to the black magic practicer, all the black magic of that guy will be automatically destroyed. For the advanced Dhamagaya, it can bring about comprehensive miracles and subdue Mara to attain the highest Dhamma state of Nipphand or Niravan.
In B.E.2493, LP Sodh started creating amulets as the gifts for donors who help him build a large Dhamma school which needed a hugh sum of money. Among the monks in his temple were worried about his project, everyone thought it's not possible to collect a large amount of money. But LP Sodh said "You all don't worry, that's my duty to do it for you. Please make your mind calm and be diligent to practice Dhamagaya I have taught you. Even it's a large building and needs a lot of money to construct, I do not work alone. Dhamagaya comes to help me and will bring me tons of money. So don't worry, you just wait and see."
It was a great amazing phenomenon, the temple flooded with people intending to donate money to him to build the school. One who donated 25 Baht would receive an amulet gift from his hand. Even a millionaire donated tens of thousands bahts, he still gave only one amulet to the donor. His nephew, the late Supreme Patriarch (Somdej Pa of Wat Bodhi) asked him "Why Luang Phor gave the millionaire only one amulet? He donated a large amount of money, could you give him 10 more amulets, couldn't you?"
LP Sodh said "You know nothing, the amulet is invaluable object, it's more valuable than any sum of money. One who receives the most sacred amulet of this kind will be rich and possesses a big treasure of a billion."
He was so strictly in distributing the amulets that no second amulet will be given to the same receiver. Once the Supreme Patriarch Somdej Pa gave his own amulet to a boy, he later requested for a new one from Luang Phor, but Luang Phor never gave him.
LP Sodh blessed his amulets by inviting all Buddhas together to charge their sacred power onto the amulets through the 3-months Lent period.
