पातञ्जल योगसूत्र (स्वामी विवेकानन्द भाष्य एवं सूत्र व्याख्या)

Patanjali Yoga Sutras disturbances come into the body; but when you have got beyond the idea of a concrete body you will lose all sense of the body. You will feel neither pleasure nor pain. And when you take your body up again it will feel so rested; it is the only perfect rest that you can give to the body. When you have succeeded in conquering the body and keeping it firm, your practice will remain firm, but while you are disturbed by the body your nerves become disturbed, and you cannot concentrate the mind. We can make the seat firm by thinking of the infinite. We cannot think of the Absolute Infinite, but we can think of the infinite sky. 47. प्रयत्नशैथिल्यानन्तसमापत्तिभ्याम् ॥ ४७॥ prayatnashaithilyanantasamapattibhyam By slight effort and meditating on the unlimited (posture becomes firm and pleasant). Light and darkness, pleasure and pain, will not then disturb you. 48. ततो द्वन्द्वानभिघातः ॥ ४८॥ tato dvandvanabhighatah Seat being conquered, the dualities do not obstruct. The dualities are good and bad, heat and cold, and all the pairs of opposites. 93
