When the enemy is knocking on the door, meditation lies in fighting, not in receding to a corner of the room closing your eyes and chanting some profound mantra.
Remember that meditation is for Liberation, meditation is not an end in itself.
Meditation that does not address and challenge the real bondages in your life, is not meditation at all.
Real Meditation is the courage to let life change.
If you keep meditating without allowing life to change, then this meditation is merely self-deception.
