Is meditation anything to do with morality or sin?
To be aware is to be virtuous. And to remain in unawareness is the only sin. You may be doing good things without awareness. But those good things are no longer good, because they come out of darkness, unconsciousness, blindness. And as far as awareness is concerned, a man who is full of awareness, alert, cannot do anything wrong. It is intrinsically impossible.
Awareness brings so much clarity, so much perception, so much understanding that it is impossible to do anything that can be harmful to anyone. It is impossible to interfere with somebody's freedom or somebody's life. You can only be a blessing to existence, nothing else. So to forget that you are a seeker is dangerous. It is falling into sin. This is the only sin I accept as sin.
