The Subtle Body is the body of refinement and helps us transcend the immediate realities of life to the sublime universal play that lies beyond. Within the Subtle Body is the awareness of the soul therefore self-awareness and it was given so we can understand. It gives us the capacity to learn quickly and relate to the nuances of life. All the intricacies of the world around us are known through this body, larger than the soul, very transparent, light and etheric in nature. If you create a powerful Subtle Body you will understand the subtleties of life, never to be trapped in perversion.
The Subtle Body and the Soul Body are intricately connected and thoughts from the Subtle Body refine the input from the soul. The soul may guide you to take certain action but the Subtle Body will refine the details of that action. It is a guardian of spirit, health and life, a sort of mothership to the soul, strengthened by meditation. Anytime you work on self-refinement you work on the Subtle Body. An example within yoga is when holding an asana or posture you are open to the Subtle Body as you intuitively refine your relationship or experience of the asana.
Finally through the Subtle Body we can access the Akashic records, the cosmic file of all thought, deed & intention and where our subconscious nature is written. Therefore it is through this body, which at the time of death our soul is carried and moves through after leaving our physical body, so we may consciously reflect our earthly existence before returning home to our supreme nature.
