The body is the external coating and the mind is the internal coating of the Atman who is the real perceiver, the real enjoyer, the being in the body who is working the body by means of the internal organ or the mind.
Swami Vivekananda"The Kingdom of Heaven is within you." Where goest thou to seek for the Kingdom of God, asks Jesus of Nazareth, when it is there, within you? Cleanse the spirit, and it is there. It is already yours. How can you get what is not yours? It is yours by right. You are the heirs of immortality, sons of the Eternal Father.
Swami Vivekananda
