This argumentation, we reply, proves nothing against our position. 'Because thus direction of the mind is declared,' i.e. because the Brahmana passage, 'Gâyatrî indeed is all this,' intimates that by means of the metre Gâyatrî the mind is to be directed on Brahman which is connected with that metre. Of the metre Gâyatrî, which is nothing but a certain special combination of syllables, it could not possibly be said that it is the Self of everything. We therefore have to understand the passage as declaring that Brahman, which, as the cause of the world, is connected with that product also whose name is Gâyatrî, is 'all this;' in accordance with that other passage which directly says, 'All this indeed is Brahman' (Kh. Up. III, 14, 1). That the effect is in reality not different from the cause, we shall prove later on, under Sûtra II, 1, 14. Devout meditation on Brahman under the form of certain effects (of Brahman) is seen to be mentioned in other passages also, so, for instance, Ait. Âr. III, 2, 3, 12, 'For the Bahvrikas consider him in the great hymn, the Adhvaryus in the sacrificial fire, the Chandogas in the Mahâvrata ceremony.' Although, therefore, the previous passage speaks of the metre, Brahman is what is meant, and the same Brahman is again referred to in the passage about the light, whose purport it is to enjoin another form of devout meditation.
Another commentator[127] is of opinion that the term Gâyatrî (does not denote Brahman in so far as viewed under the form of Gâyatrî, but) directly denotes Brahman, on account of the equality of number; for just as the Gâyatrî metre has four feet consisting of six syllables each, so Brahman also has four feet, (i.e. quarters.) Similarly we see that in other passages also the names of metres are used to denote other things which resemble those metres in certain numerical relations; cp. for instance, Ch. Up. IV, 3, 8, where it is said at first, 'Now these five and the other five make ten and that is the Krita,' and after that 'these are again the Virâj which eats the food.' If we adopt this interpretation, Brahman only is spoken of, and the metre is not referred to at all. In any case Brahman is the subject with which the previous passage is concerned.
26. And thus also (we must conclude, viz. that Brahman is the subject of the previous passage), because (thus only) the declaration as to the beings, &c. being the feet is possible.
That the previous passage has Brahman for its topic, we must assume for that reason also that the text designates the beings and so on as the feet of Gâyatrî. For the text at first speaks of the beings, the earth, the body, and the heart[128], and then goes on 'that Gâyatrî has four feet and is sixfold.' For of the mere metre, without any reference to Brahman, it would be impossible to say that the beings and so on are its feet. Moreover, if Brahman were not meant, there would be no room for the verse, 'Such is the greatness,' &c. For that verse clearly describes Brahman in its own nature; otherwise it would be impossible to represent the Gâyatrî as the Self of everything as is done in the words, 'One foot of it are all the beings; three feet of it are what is immortal in heaven.' The purusha-sûkta also (Rik Samh. X, 90) exhibits the verse with sole reference to Brahman. Smriti likewise ascribes to Brahman a like nature, 'I stand supporting all this world by a single portion of myself' (Bha. Gîtâ X, 42). Our interpretation moreover enables us to take the passage, 'that Brahman indeed which,' &c. (III, 12, 7), in its primary sense, (i.e. to understand the word Brahman to denote nothing but Brahman.) And, moreover, the passage, 'these are the five men of Brahman' (III, 13, 6), is appropriate only if the former passage about the Gâyatrî is taken as referring to Brahman (for otherwise the 'Brahman' in 'men of Brahman' would not be connected with the previous topic). Hence Brahman is to be considered as the subject-matter of the previous passage also. And the decision that the same Brahman is referred to in the passage about the light where it is recognised (to be the same) from its connexion with heaven, remains unshaken.
27. The objection that (the Brahman of the former passage cannot be recognised in the latter) on account of the difference of designation, is not valid because in either (designation) there is nothing contrary (to the recognition).
The objection that in the former passage ('three feet of it are what is immortal in heaven'), heaven is designated as the abode, while in the latter passage ('that light which shines above this heaven'), heaven is designated as the boundary, and that, on account of this difference of designation, the subject-matter of the former passage cannot be recognised in the latter, must likewise be refuted. This we do by remarking that in either designation nothing is contrary to the recognition. Just as in ordinary language a falcon, although in contact with the top of a tree, is not only said to be on the tree but also above the tree, so Brahman also, although being in heaven, is here referred to as being beyond heaven as well.
Another (commentator) explains: just as in ordinary language a falcon, although not in contact with the top of a tree, is not only said to be above the top of the tree but also on the top of the tree, so Brahman also, which is in reality beyond heaven, is (in the former of the two passages) said to be in heaven. Therefore the Brahman spoken of in the former passage can be recognised in the latter also, and it remains therefore a settled conclusion that the word 'light' denotes Brahman.
28. prâna (breath) is Brahman, that being understood from a connected consideration (of the passages referring to prâna).
In the Kaushîtaki-brâhmana-upanishad there is recorded a legend of Indra and Pratardana which begins with the words, 'Pratardana, forsooth, the son of Divodâsa came by means of fighting and strength to the beloved abode of Indra' (Kau. Up. III, 1). In this legend we read: 'He said: I am prâna, the intelligent Self (prajñâtman), meditate on me as Life, as Immortality' (III, 2). And later on (III, 3), 'prâna alone, the intelligent Self, having laid hold of this body, makes it rise up.' Then, again (III, 8), 'Let no man try to find out what speech is, let him know the speaker.' And in the end (III, 8), 'That breath indeed is the intelligent Self, bliss, imperishable, immortal.'—Here the doubt presents itself whether the word prâna denotes merely breath, the modification of air, or the Self of some divinity, or the individual soul, or the highest Brahman.—But, it will be said at the outset, the Sûtra I, 1, 21 already has shown that the word prâna refers to Brahman, and as here also we meet with characteristic marks of Brahman, viz. the words 'bliss, imperishable, immortal,' what reason is there for again raising the same doubt?—We reply: Because there are observed here characteristic marks of different kinds. For in the legend we meet not only with marks indicating Brahman, but also with marks pointing to other beings Thus Indra's words, 'Know me only' (III, 1) point to the Self of a divinity; the words, 'Having laid hold of this body it makes it rise up,' point to the breath; the words, 'Let no man try to find out what speech is, let him know the speaker,' point to the individual soul. There is thus room for doubt.
