Spirituality is, in its essence, an awakening to the inner reality of our being, to a spirit, self, soul which is other than our mind, life, and body; an inner aspiration to know, to feel, to be that, to enter into contact with the greater Reality beyond and pervading the universe which inhabits also our own being.
