Buddha did not mean right as opposed to wrong at all. Right means being right without a concept of what is right. Right translates into the Sanskrit samyak, which means "complete". Completeness needs no relative help, no support through comparison; it is self-sufficient. Samyak means seeing life as it is without crutches, straightforwardly. In a bar, one may say, "I would like a straight drink." Not diluted with club soda or water; you just have it straight. That is samyak. No dilutions, no concoctions—just a straight drink. Buddha realized that life could be potent and delicious, positive and creative, and he realized that you do not need any concoctions with which to mix it. Life is a straight drink—straight pleasure, straight pain, straightforward, one hundred percent.
