How and when can one feel the Mother‘s concrete presence all the time?
It is a matter, first, of the constant activity of the psychic and secondly of the conversion of the physical and its openness to inner supraphysical experience. Apart from the vital and its disturbances the physical is the chief difficulty in establishing a continuity of Yogic consciousness and experience. If the physical is thoroughly transformed—opened and conscious—then stability and continuity become easy.
