The mind not should seek to control the body.
The mind can perhaps control the body, and suppress the senses, but thereby the mind makes the body insensitive; and an insensitive body becomes a hindrance for the own full unfolding of the mind.
To restrain the body certainly doesn´t serve the investigation of the deeper layers of consciousness.
This is only possible when there doesn't exist a conflict between the mind, the feelings and the body.
It is only possible when they are complete, and in mutual harmony, and are this in an effortless way, without becoming drifted to it by some specific images of life, a particular conception, belief or ideal.
