"The Rabbi of Kotzk once asked one of his disciplines, 'Where is God?'
The disciple answered, 'Why, of course, he is everywhere!'
The Rabbi of Kotzk shook his head and said, 'Not so. He is only where He is allowed to enter.'
It may be concluded that the person who permits God to come into him is the one who is close to God.
There is no need to draw and pull God to oneself or to climb and struggle to Him.
One has only to allow Him to be present, or at least one's actions have to be such that God can participate in them."
