Natural, deep, dreamless sleep is a miraculous healer. Any approximation of that ‘state’ during waking hours is a crucial activity of the body-mind. This is where meditation is such a vital (non)activity.
Life – Knowingness, Awareness, Primordial Essence, God, Tao; as you wish – is unhampered by the web of confused and conflicting concepts called thought and experienced as self.
IT simply lives ITs vast vitality; runs repairs on the body-mind as necessary, blessedly unimpeded by a ‘doer’ doing anything.
