I've been a buddhist my entire life, and I've never seen these categories of 3 before. Well, except for Buddha, Dharma, and Sangha.
This is all very interesting for me because I go to a Jodo Shu church which is based in Japan. We learned the 8-Fold Path, Golden Chain, and the 4 Noble Truths growing up. I suppose we never got really deep into some other teachings because I didn't recognize a lot of words in the alphabet game. <img src="/images/graemlins/blush.gif" alt="" /> Or maybe it's just a language thing.
Anyhoo, can you explain 3 Realms to me please. Thanks!
