Sup Crash, I should be leaving for Pattaya right now, but I figured 30 minutes of forum-ing won't hurt.
Sak-yant, did that before. On my right forearm. but you can't see it as I did it with holy oil, not ink. I did something called "maht tanu" or "arrow fist". Supposed to enchance striking power and go through any defense. Does it work? Sometimes.
Sak-yant are hard to keep them working. There are some rules that you can't break, if you do, the effects goes off. For example, if you have "Nai Kanomtom" on your back, when in times of danger, you'll have his skills. But if I was to throw my shoe on your head, the effects goes off. Thais are very superstitious when it comes to head and feet. It's considered a big taboo to touch someone head with your foot, that's why MT boxers kicks with their shins. Understand?
No touching of the head with feets or shoes.
No walking across the tattooed guy when he's lying down.
No desecration to the Lord Buddha.
No tampering with the sak-yants.
No consumption of animal flesh (for some)
No disrespect towards your parents.
And failure to uphold the 5 sin (not sins!), or buddhist rules will make the sak-yants powerless.
For example, my sak-yant is powerless because while I was driving on my bike, I drove under a bridge, and people were walking across it.
See why it's so hard to uphold Sak-yant's power?
Yants, or Yantra in pali, are very spiritual. Many boxers does them in belief they'll be able to last until the end of their careers. Imagine having weekly fights and hard training regime. It's better to get less injured, than to get healed slowly.
Sak-yants can be made in ink or oil. Depends on what the wearer likes. I've only done maht tanu on my right fore-arm. My uncle did Hanuman on his back, leaping tiger on his chest, maht tanu on both forearms and a turtle on his neck. Thanks god it was with oil and not ink.
So Crash, are you part Asian? I never heard of a Buddhist white boy before except Richard Gere.
