971. Parimitam Kalam is explained by the commentator as equivalent to six months as the srutis declare.
972. These two verses set forth the Yoga ideal. By the practice of Yoga all these are capable of being acquired or attained. But then the Yogin who suffers himself to be led away by those valuable possessions is said to fall in hell, for the enjoyment of this kind is nothing but hell compared to the high object for which Yogins should strive. Pramoha, Brahma, and Avarta, are technical terms. Equality with the wind means speed of motion, power to disappear at will, and capacity to move through the skies.
973. A chaitya is a sacred or a large tree which stands firm on its roots and about which all round a platform of earth is raised. Vrikshagra means 'in the front of a tree,' probably implying 'under the shade of its spreading branches.'
974. The commentator explains that he should imitate the wind by becoming asangah, i.e., unattached to all things. Aniketah means without a house or fixed abode.
975. It is difficult to understand what is meant by Savda-Brahmativartate. I follow the commentator. 'Brahma as represented by sound, is, of course, Pranavah or Om, the mystic monosyllable standing for the trinity.' K.P. Singha, taking Savda-Brahma for an accusative, regards it as implying,—'such a man transcends all Vedic rites.' This is precisely the meaning attached to it by the commentator where it occurs in verse 7 of section 236 ante.
976. The inferior order here referred to is, of course, the Sudra order. The commentator points out that whereas only the three superior orders are regarded to be eligible for the study of Sankhya and for inculcation of such Srutis as Tattwamasi (That thou art), here Vyasa lays down that as regards the Yoga path, all are eligible to betake themselves to it.
977. 'Fixed senses,' i.e., when the senses are fixed on the mind and the mind on the understanding. Ajaram is immutable or unchanging, or that in which there is no change for the worse (or for the better). By subtility is indicated the incapacity of being apprehended, and by mahattaram is meant infinity.
978. The anu anudrisya is explained as Guruvachanamanu. Thus seems to be the true meaning, otherwise avekshya would be pleonastic, abhutagatim is bhutasamplavaparyantam, i.e., till the destruction of all beings. Imam is sastraprasiddham.
979. The Vedas proclaim the efficacy of both acts and knowledge. Acts are not laid down for those that have knowledge.
980. Subhashita is explained by the commentator as ayam tu paramo dharma yat yogena atmadarsanam.
