The very essence of creatureliness is the feeling of being separate, of being itself.
And this capacity of a thing to be itself, even though its very life and existence, physically and spiritually, are incessantly dependent on Divine mercy, on His Chesed, is the miracle of His concealment, His apparent withdrawal.
It is as though a person's arm were to begin to talk back to him and say, "I want this. I do not want that."
Our various organs are a part of the world, they belong to the things in the world, yet they cannot be said to have a feeling of independence, nor do they feel that they are something in themselves.
–Rabbi Adin Steinsaltz
