He keeps it as a training and allows only the ascetic to be a philosopher indeed.

But at the same time he gives as a sort of peroration to his treatise some 'elegant extracts' from philosophical works, which he believes theoretically, although practically he will not allow them to influence his ritualism.

He is a true Brahman priest.
It is this that is always so annoying in Brahmanic philosophy.

For the slavery of tradition is everywhere.

Not only does the ritualist, while admitting the force of the philosopher's reasons, remain by Vedic tradition, and in consequence refuse to supplant 'revelation' with the higher wisdom and better religion, which he sees while he will not follow it; but even the philosopher must needs be 'orthodox,' and, since the scriptures themselves are self-contradictory, he is obliged to use his energies not in discovering truth, but in reconciling his ancestors' dogmas, in order to the creation of a philosophical system which shall agree with everything that has been said in the Vedas and Upanishads.
