As declared by the great teachings—'You are That', 'I am the absolute', 'All this manifest world is the Self', 'This very Self is Brahman', and 'The knower of the Self crosses beyond all sorrow'—and confirmed by scripture, tradition, epic, myth, and daily reason: 'What delusion, what grief can touch the one who sees nothing but oneness?'
