In English
You put a lock on the door. To open the lock, you insert the key and turn it to the right. Then the lock opens. To lock it, you turn the key to the left. The same lock, the same key. The difference is only in turning right or left. In the same way, heart is the lock, mind is the key. Turn God-side, you get detachment; turn world-side, you get attachment. Turn the mind toward God, you get liberation. Turn the mind toward the world, you get bondage. So, the mind is responsible for both liberation and bondage.
