The Book After the death of the physical body, the mind remains inactive for some time, as in dreamless sleep when it remains wordless and therefore bodiless. But soon it becomes active again in a new world and a new body the astral till it assumes another body in what is called a rebirth. Sage Sri Ramana Maharshi Based on the teachings of Sri Ramana Maharshi, Life Beyond Death explores other lives, delving deep into the mysteries of the astral, mental and other higher planes of existence.
