1301. i.e., by abandoning all kinds of idleness, as explained by the commentator.
1302. i.e., by Yoga-meditation one should regulate and finally suspend one's breath. The Yogin can suspend all physical functions and yet live on from age to age.
1303. Nidra here is explained as ananusandhana or the absence of inquisitiveness or curiosity. By pratibha is meant inquiry after improper things or things that are of no interest.
1304. The truth is that the world is unreal and has no end.
1305. Hunger is to be subdued by Yoga, i.e., by regulating the wind within the body. Doubt is to be dispelled by certainty; this implies that certain knowledge should be sought for by driving off doubt. The commentator thinks that this means that all sceptical conclusions should be dispelled by faith in the scriptures. By 'fear,' in this verse, is meant the source of fear, or the world. That is to be conquered by the conquest of the six, i.e., desire, wrath, covetousness, error, pride, and envy.
1306. What is laid down here is the same course of training that is indicated for Yoga. First, the senses are to be merged into the mind, then the mind is to be merged into the Understanding, then the Understanding is to be merged into the Soul or what is known as the Ego. This Ego is to be merged at last into the Supreme Soul. When the Ego is understood, it comes to be viewed as Brahma.
1307. 'Pure acts' are, of course, those that are included in 'Nishkama dharmah,' and 'tranquillity of soul' is the cleansing of the soul by driving away all passions and desires.
1308. Such restraint of speech, etc., or niyamah is yogah. Kamaoanyatha is kama-vaiparityena. The sense, the commentator adds, is that one should not desire 'yoga-siddhi,' for then, as has been repeatedly indicated in the previous Sections, the Yogin would fall into hell and succeed not in attaining to Emancipation, heaven itself being hell in comparison with the felicity of Emancipation. K.P. Singha quietly skips over the last line and the Burdwan translator offers a ridiculously incorrect version.
1309. Yebhyah means 'the materials from which.' (Srijati) has Paramatma for its nominative (understood). Kale is the time of creation as selected by the Supreme Soul in his own wisdom. Bhavaprachoditah is 'induced by the desire of becoming many, or led by the desire of existence as many or in infinite diversity.'
1310. Kala here is, perhaps, the embodiment of the abstract idea of life of living creatures. Impelled by the Understanding, Kala or life sets itself to the creation of other creatures. These last also are equally the result of the same five primal essences.
