It's not a question of reward or punishment. It is simply your consciousness, your silence, your peace, which makes you look so far away and so deep into everything that you do. You cannot do harm to anybody; you cannot be violent: you cannot be angry, you cannot be greedy, you cannot be ambitious. Your consciousness has given you so much blissfulness...what can greed give you except anxiety? What can ambition give you? Just a continuous struggle to reach high on some ladder.
As your consciousness becomes more settled, all your life patterns change. What religions have called sin will disappear from your life, and what they have called virtue will automatically flow from your being, from your actions. But they have been doing just vice versa: first change the acts. It is as if you are in a dark house and you are stumbling, light is not possible. What I am saying is, bring light in and stumbling will disappear, because when there is light why should you stumble over things?
Every time you stumble, every time you hit your head on a wall it hurts. It is a punishment in itself - a wrong act is a punishment in itself; there is nobody recording your acts. And every beautiful action is a reward unto itself. But first bring light into your life.
Meditation is an effort to bring light and to bring joy and to bring silence and to bring blissfulness, and out of this beautiful world of meditation it is impossible for you to do anything wrong.
