Sak Yant or Yantra Tattooing are believed to give the wearer magic powers associated with healing, luck, strength, and protection against evil.
You can get these here in thailand by a monk, they look beautiful but I’d never recommend it. Essentially, you’re making a pact with a spirit to protect you in exchange for sacrificing an activity or habit you may have previously enjoyed (the monk decides what this is, not you). These tattoos are contracts. Breaking your side of the bargain may encourage the spirit to ‘punish’ you, and these contracts are not easily voided.
500 kg of Epsom salts are added to 1000 litres of water, creating a 30 cm deep solution, which is heated to 35.5 degrees C (skin temperature).
The temperature of the water means that once you are settled in the tank, it is virtually impossible to distinguish between parts of the body that are in contact with the water, and those that aren’t, in effect “fooling” the brain into believing that the person is floating in mid-air.
