Q. What is the relation between soul and body; soul and mind; body and mind: sufferings of soul; suffering of body?
A. The body is like a vehicle or machine upon which the soul is seated. There is nice analogy in Katha Upanisad which describes the body as the chariot, the senses as the horses, the mind as the driving instrument, the intelligence as the driver of the chariot, and the soul is riding on this chariot. The soul actually experiences neither enjoyment or suffering in this material region, because it is spiritual by nature, and is full of eternity, knowledge and bliss. However, the soul experiences the pains and pleasures of the body, which are just material interactions, because he is thinking he is this body. The suffering or enjoyment of the soul is just like one’s suffering in a dream; it has no reality. Cf BG 13.21 and 22.
