I would like to share with everyone a Buddhist perspective.
Basically, Buddhism advises against any kind of mind-altering substance, including alcohol.
This isn't for "moral" reasons of any kind. Basically, the Buddhist idea is that you should keep your mind as clear as possible, so that you can perceive reality more accurately.
Of course, Buddhism also says that to begin with, practically all of us already have murky, clouded brains (even when we don't take any substances).
Enlightenment is when your mind becomes completely clear and you can perceive reality as it is.
Now, what that is - don't ask me. I'm still pretty clouded.
Must be my coffee.
