this was not the definition i read( i read ‘moderation of the senses’)
I don’t now where you read this, and it’s not surprising, because people just don’t want to accept the true meaning of the word. My philosophy is to try to get the true meaning of the original authors. One is free to accept or reject the teaching, but don’t distort the meaning just because you don’t accept it.
If you look at the context of the sutra where the teaching of brahmacharya is given, its about the restraint of various types of harmful impulses. Brahmacharya is specifically about the sexual impulse. In the strictest sense, it is about sexual continence, plain and simple. I believe the definition can be broadened to include other types of sexual conduct, such as how one conducts him/her self with members of the opposite sex. But moderation of the senses is way too broad.
I know someone is going to say that sexual desire is not a harmful impulse, but just pick up a newspaper on any given day and you are likely to see reports of all kinds of bad behavior and even violence that results from uncontrolled sexual impulses. Self-control is important, and has lots of positive effects. Wise use of creative force is good.
