Is this union with the highest Self to be understood as ordinary 'merging,' i.e. a return on the part of the effected thing into the condition of the cause (as when the jar is reduced to the condition of a lump of clay), or as absolute non-division from the highest Self, such as is meant in the clauses preceding the text last quoted, 'Speech is merged in mind'? &c.—The former view is to be adopted; for as the highest Self is the causal substance of all, union with it means the return on the part of individual beings into the condition of that causal substance.—This view the Sûtra rejects. Union here means non- division, i.e. connexion of such kind that those subtle elements are altogether incapable of being thought and spoken of as separate from Brahman. This the text itself declares, since the clause 'warmth in the highest Being' is connected with and governed by the preceding clause 'Speech is merged in mind.' This preceding clause intimates a special kind of connexion, viz. absolute non-separation, and there is nothing to prove that the dependent clause means to express something different; nor is there any reason why at the time of the soul's departure those elements should enter into the causal condition; nor is there anything said about their again proceeding from the causal substance in a new creation.—Here terminates the adhikarana of 'non-separation.'
16. A lighting up of the point of the abode of that; having the door illuminated by that (the soul), owing to the power of its knowledge and the application of remembrance of the way which is an element of that (viz. of knowledge), being assisted by him who abides within the heart, (passes out) by way of the hundred and first artery.
So far it has been shown that, up to the beginning of the journey, the souls of them as well who possess true knowledge as of those who do not, pass out of the body in the same way. Now a difference is stated in the case of those who have true knowledge. We have on this point the following text: 'There are a hundred and one arteries of the heart; one of them penetrates the crown of the head; moving upwards by that a man reaches immortality; the others serve for departing in different directions' (Ch. Up. VIII, 6, 5). The doubt here arises whether he who knows departs by this hundred and first artery in the top of the head, while those who do not know depart by way of the other arteries; or whether there is no definite rule on this point.—There is no definite rule, the Pûrvapakshin holds. For as the arteries are many and exceedingly minute, they are difficult to distinguish, and the soul therefore is not able to follow any particular one. The text therefore (is not meant to make an original authoritative statement as to different arteries being followed by different souls, but) merely refers in an informal way to what is already settled (viz. by the reason of the thing), i.e. the casual departure of any soul by any artery.—This view the Sûtra rejects 'By way of the hundred and first.' The soul of him who possesses true knowledge departs only by way of the hundred and first artery in the crown of the head. Nor is that soul unable to distinguish that particular artcry. For, through the power of his supremely clear knowledge which has the effect of pleasing the Supreme Person, and through the application of remembrance of the way—which remembrance is a part of that knowledge—the soul of him who knows wins the favour of the Supreme Person who abides within the heart, and is assisted by him. Owing to this the abode of that, i.e. the heart which is the abode of the soul, is illuminated, lit up at its tip, and thus, through the grace of the Supreme Soul, the individual soul has the door (of egress from the body) lit up and is able to recognise that artery. There is thus no objection to the view that the soul of him who knows passes out by way of that particular artery only.—Here terminates the adhikarana of 'the abode of that.'
17. Following the rays.
Scripture teaches that the soul of him who knows, after having passed forth from the heart by way of the hundred and first artery, follows the rays of the sun and thus reaches the disc of the sun: 'when he departs from this body he goes upwards by these rays only' (eva) (Ch. Up. VIII, 6, 5). The idea here suggests itself that the going of the soul cannot be exclusively bound' to those rays, since when a man dies during the night it cannot follow tae rays of the sun. Hence the text quoted above can refer only to a part of the actual cases.—This view the Sûtra rejects. The soul moves upwards, following the rays only; the text expressly asserting this by means of the 'eva'—which would be out of place were there any alternative. Nor is there any strength in the argument that the soul of him who dies at night cannot follow the rays as there are none. For in summer the experience of heat at night-time shows that there are present rays then also; while in winter, as generally in bad weather, that heat is overpowered by cold and hence is not perceived (although actually present). Scripture moreover states that the arteries and rays are at all times mutually connected: 'As a very long highway goes to two villages, so the rays of the sun go to both worlds, to this one and to the other. They stretch themselves forth from the sun and enter into these arteries'; they stretch themselves forth from these arteries and enter into yonder sun' (Ch. Up. VIII, 6, 2).—As thus there are rays at night also, the souls of those who know reach Brahman by way of the rays only.—Here terminates the adhikarana of 'the following up the rays.'
18. Should it be said, not in the night; we say, no; because the connexion persists as long as the body does. Scripture also declares this.
It is now enquired into whether the soul of him who, while having true knowledge, dies at night reaches Brahman or not. Although, as solar rays exist at night, the soul may move on at night also following those rays; yet, since dying at night is spoken of in the Sûtras as highly objectionable, we conclude that he who dies at night cannot accomplish the highest end of man, viz. attainment to Brahman. The Sûtras eulogize death occurring in daytime and object to death at night-time: 'Day-time, the bright half of the month and the northern progress of the sun are excellent for those about to die; the contrary times are unfavourable.' According to this, their different nature, dying in day-time may be assumed to lead to a superior state of existence, and dying at night to an inferior state. He who dies at night cannot therefore ascend to Brahman.—This view the Sûtra refutes: 'Because, in the case of him who knows, the connexion with works exists as long as the body does.' This is to say—since those works which have not yet begun to produce their results and which are the cause of future inferior states of existence are destroyed by the contact with knowledge, while at the same time later works do not 'cling' (also owing to the presence of true knowledge), and those works which have begun to act come to an end with the existence of the last body; there is no reason why he who knows should remain in bondage, and hence he reaches Brahman even if dying at night-time. Scripture also declares this, 'for him there is delay only as long as he is not freed from the body, then he will be united.' The text which praises the advantages of night-time, the light half of the month, &c., therefore must be understood as referring to those who do not possess true knowledge.—Here terminates the adhikarana of 'night.'
19. For the same reason also during the southern progress of the sun.
The reasoning stated above also proves that the owner of true knowledge who may happen to die during the southern progress of the sun reaches Brahman. A further doubt, however, arises here. The text 'He who dies during the sun's southern progress reaches the greatness of the Fathers and union with the moon' (Mahânâr. Up. 25) declares that he who dies during the southern progress reaches the moon; and the other text 'when this ceases they return again the same way' (Bri. Up. VI, 2, 16) states that he returns again to the earth. We further know that Bhîshma and others, although fully possessing the knowledge of Brahman, put off their death until the beginning of the northern progress. All this seems to prove that he who dies during the southern progress does not reach Brahman.—This doubt we dispose of as follows. Those only who do not possess true knowledge return from the moon; while he who has such knowledge does not return even after he has gone to the moon. For a complementary clause in the Mahânârâyana Up., 'from there he reaches the greatness of Brahman,' shows that the abode in the moon forms for him, who having died during the southern progress wishes to reach Brahman, a mere stage of rest. And even if there were no such complementary passage, it would follow from the previously stated absence of any reason for bondage that the going of the wise man's soul to the moon in no way precludes his reaching Brahman. Bhîshma and others who through the power of Yoga were able to choose the time of their death put it off until the beginning of the northern progress in order to proclaim before the world the excellence of that season and thus to promote pious faith and practice.—But we also meet with an authoritative statement made with reference to wise men about to die, as to difference of time of death being the cause of a man either returning or not returning to this world, 'I will declare at which time the Yogins departing return not, and also the time at which they return. The sire, the light, the day, the bright fortnight, the six months of the sun's northern progress—the knowers of Brahman departing there go to Brahman. The smoke, the night, the dark fortnight, the six months of the southern progress—the Yogin departing there having reached the light of the moon returns again. These are held to be the perpetual paths of the world—the white and the black; by the one man goes not to return, by the other he returns again' (Bha. Gî. VIII, 23-26).—To this point the next Sûtra refers.
20. And those two (paths) are, with a view to the Yogins, mentioned as to be remembered.
