Those who seek to realise the subtler purposes of life including human nature can find a clear starting point in the ancient yogic science focussed upon the study of all the component spheres in which human consciousness moves in life experience.
The physical body is the starting point, from which we extend to consider our invisible but very real energy body or sheath. In progressive study and concentration we graduate to become aware of our emotional body with its depths and variations of feeling and mood. We cannot see it, but we know that our emotions are very real. Then step by step in finer and finer layers of ourselves we identify ourselves beyond emotions and thought to our innermost soul body – our immortal part of us that is ‘the experiencer’ in our lives.
