This Jin Gang mineral healing stone was obtained by Luang Por Thong Gleung Sunataro of Wat Pathum Thani Chedi Hoi, Thailand. In order to use this Jin Gang stone, one should take a pan with boiled hot water and place the stone inside the pan, so that it can absorb the heat and charge its energies. Once the water is vaporated, the Jin Gang needs to cool down from the heat first. However, the stone must not be cooled off completely; it should be placed in your hand while it is still hot (but not too hot, of course) so that it can transfer the subtle energies into your own body through absorption via the bloodvessels in your hand. It is generally believed that this will reduce physical pains (rheuma and the like), as well as restoring the inner balance of subtle energies within the human body.
