The meditation, for instance, on man and woman as fire, which is founded on Ch. Up. V, 7, 1; 8, 1, 'The fire is man, O Gautama; the fire is woman, O Gautama,' is on account of its being the result of a Vedic statement, merely an action and dependent on man; that conception of fire, on the other hand, which refers to the well-known (real) fire, is neither dependent on Vedic statements nor on man, but only on a real thing which is an object of perception; it is therefore knowledge and not an action. The same remark applies to all things which are the objects of the different means of right knowledge. This being thus that knowledge also which has the existent Brahman for its object is not dependent on Vedic injunction. Hence, although imperative and similar forms referring to the knowledge of Brahman are found in the Vedic texts, yet they are ineffective because they refer to something which cannot be enjoined, just as the edge of a razor becomes blunt when it is applied to a stone. For they have for their object something which can neither be endeavoured after nor avoided.--But what then, it will be asked, is the purport of those sentences which, at any rate, have the appearance of injunctions; such as, 'The Self is to be seen, to be heard about?'--They have the purport, we reply, of diverting (men) from the objects of natural activity. For when a man acts intent on external things, and only anxious to attain the objects of his desire and to eschew the objects of his aversion, and does not thereby reach the highest aim of man although desirous of attaining it; such texts as the one quoted divert him from the objects of natural activity and turn the stream of his thoughts on the inward (the highest) Self. That for him who is engaged in the enquiry into the Self, the true nature of the Self is nothing either to be endeavoured after or to be avoided, we learn from texts such as the following: 'This everything, all is that Self' (B/ri/, Up. II, 4, 6); 'But when the Self only is all this, how should he see another, how should he know another, how should he know the knower?' (B/ri/. Up. IV, 5, 15); 'This Self is Brahman' (B/ri/. Up. II, 5, 19). That the knowledge of Brahman refers to something which is not a thing to be done, and therefore is not concerned either with the pursuit or the avoidance of any object, is the very thing we admit; for just that constitutes our glory, that as soon as we comprehend Brahman, all our duties come to an end and all our work is over. Thus /S/ruti says, 'If a man understands the Self, saying, "I am he," what could he wish or desire that he should pine after the body?' (B/ri/. Up. IV, 4, 12.) And similarly Sm/ri/ti declares, 'Having understood this the understanding man has done with all work, O Bharata' (Bha. Gita XV, 20). Therefore Brahman is not represented as the object of injunctions.
