Finding the Self

"Self is everywhere, shining forth from all beings, vaster than the vast, subtler than the most subtle, unreachable, yet nearer than breath, than heartbeat. Eye cannot see it, ear cannot hear it nor tongue utter it; only in deep absorption can the mind, grown pure and silent, merge with the formless truth. He who finds it is free; he has found himself; he has solved the great riddle; his heart forever is at peace. Whole, he enters the Whole. His personal self returns to its radiant, intimate, deathless source."
