Luang Pu Khampan Khosàpanyo
The Renowned "stones" from Mekong river. There is no way to know which is touched by Luang Pu and which isn't. And these are entirely different from Amulets consecration. They cannot be consecrated no matter how High or how "powerful" one had reached.
Luang Pu once said these Patthawee That can only be "invoked" (I hope that's the correct word) by One who had reached a very High level of "Gammathan", which I think meant a seriously High meditative level of the mind.
Only 3 Masters were able to "invoke" these Stones. And Luang Pu was predicted and foretold by the most famous of all, Jao Khun Nor of Wat Thep Sirin.
These Stones are believe to give really strong protection even from radiation as Luang Pu predicted the future, mankind would be facing these serious threats. When we thought Luang Pu had predicted a War, it was actually the ocean 😭😓
