Thoughts Form the Physical Body
The body with its organs is no other than the thought. The mind contemplating upon the body becomes the body itself, and then enmeshed in it, is afflicted by it.
This physical body is the mould as it were, made by the mind for its own enjoyment, for its outpouring of energy and thereby gaining different experiences of this world through the five avenues or channels of knowledge, the five Jnana-Indriyas (organs of knowledge or perception). The body is really our thoughts, moods, convictions and emotions objectified, made visible to the naked eyes.
All the bodies have their seat in the mind only. Without water can a garden exist?
It is the mind which transacts all business and is the highest of bodies. Should this gross body be dissolved, the mind will assume fresh bodies to its liking very quickly. Should the mind be paralyzed, then the body will not evince our intelligence.
With the majority of mankind, the thought is greatly under the control of the body. Their minds being very little developed, they live in Annamaya Kosa, mostly. Develop the Vijnanamaya Kosa and through Vijnanamaya Kosa (Buddhi) control the Manomaya Kosa (mind).
The erroneous thought that you are the body is the root of all evils. Through wrong thinking you identify yourself with the body. Dehadhyasa arises. You are attached to the body. This is Abhimana. Then Mamata (mine-ness) arises. You identify yourself with your wife, children, house, etc. It is identification or attachment that brings about bondage, misery and pain.
