37. And because all the qualities (required in the cause of the world) are present (in Brahman).
The teacher has now refuted all the objections, such as difference of character, and the like, which other teachers have brought forward against what he had established as the real sense of the Veda, viz. that the intelligent Brahman is the cause and matter of this world.
Now, before entering on a new chapter, whose chief aim it will be to refute the (positive) opinions held by other teachers, he sums up the foregoing chapter, the purport of which
it was to show why his view should be accepted.--Because, if that Brahman is acknowledged as the cause of the world, all attributes required in the cause (of the world) are seen to be present--Brahman being all-knowing, all-powerful, and possessing the great power of Mâyâ,--on that account this our system, founded on the Upanishads, is not open to any objections.
