Yoga Sutra 2.41 fitness for vision of the self

Sūtra II.41 Purity of mind-sattva, cheerfulness, one-pointedness, conquest of the senses, and fitness for vision of the self The words ‘There arise’ should be supplied at the beginning of the sūtra. There arises purity of mind-sattva, and from that arises cheerfulness; from that, one-pointedness; from that, conquest of the senses; and from that, fitness of mind-sattva for vision of the self which thus is attained from firmness in purity. What else happens? There arise purity of mind-sattva, cheerfulness, one-pointedness, conquest of the senses, and fitness for vision of the self. As each earlier one becomes firm, the succeeding one appears. From purity there arises purity of mind-sattva, and from that arises cheerfulness; from that, one-pointedness; from that, conquest of the senses; and from that, fitness of mind-sattva for vision of the self It is all attained from firmness in purity, and it is this which is the perfection of purity.
