46. But it is a meditation only, on account of assertion and what is seen.
The altars built of mind, and so on, are not of the nature of action, but of meditation only, i.e. they belong to a performance which is of the nature of meditation only. For this is what the text asserts, viz. in the clauses 'they are built of knowledge only,' and 'by knowledge they are built for him who thus knows.' As the energies of mind, speech, sight, and so on, cannot be piled up like bricks, it is indeed a matter of course that the so-called altars constructed of mind, and so on, can be mental constructions only; but the text in addition specially confirms this by declaring that those altars are elements in an activity of purely intellectual character, and hence themselves mere creatures of the intellect. Moreover there is seen in the text a performance consisting of thought only to which those fires stand in a subsidiary relation, 'by the mind they were established on hearths, by the mind they were built up, by the mind the Soma cups were drawn thereat;

by the mind they chanted, and by the mind they recited; whatever rite is performed at the sacrifice, whatever sacrificial rite there is, that, as consisting of mind, was performed by the mind only, on those (fire-altars) composed of mind, built up of mind.' From this declaration, that whatever sacrificial rite is actually performed in the case of fire-altars built of bricks is performed mentally only in the case of altars built of mind, it follows that the entire performance is a mental one only, i.e. an act of meditation.--But, an objection is raised, as the entire passus regarding the altars of mind does not contain any word of injunctive power, and as the text states no special result (from which it appears to follow that the passus does not enjoin a new independent performance), we must, on the strength of the fact that the leading subject-matter is an actual sacrificial performance as suggested by the altars built of brick, give up the idea that the altars built of mind, &c., are mental only because connected with a performance of merely mental nature.--This objection the next Sûtra refutes.
