Step by step, not all at once, let him come to rest. By what understanding? By one held firm, held firm by steadiness, that is, joined with steadiness. Making the mind settled in the Self, settled in the conviction that the Self alone is everything and nothing else exists apart from it, let him think of nothing whatever. This is the highest discipline of yoga. Now, of the yogin who has set out to make the mind settled in the Self in this way.
