Your torch of consciousness should be burning continuously; then there will not be any darkness.
Meditation is not doing anything directly to your violence, not doing anything to your jealousy, to your hate. It is simply bringing light into your house, and the darkness disappears.
The ego is nothing but condensed unawareness. When you become aware by and by that condensed unawareness we call 'ego' disappears. Just as if you bring a lamp into the room - and the darkness disappears. Awareness is the lamp, the lamp we were talking about the first day. Be a lamp unto yourself.
