The System of the Vedanta according to Badarayana's Brahma-Sutras and Cankara's Commentary c8.s3.t3.8

c8.s3.t3.8

"But if the sage has no duties, can he do what he will?"—Not at all! For it is only illusion that moves to action and it is just this illusion that exists no more for this sage.—But in spite of the unity of all existence, command and prohibition exist for him who has not attained knowledge. For as one shrinks from the fire which has burnt a corpse, though it is as much fire as any other—as one avoids sunlight in unclean places, though it comes just as much from the sun—as one flees from a human corpse though it consists of the same materials as the living body—so there are certain things to be avoided, though all things are one in the Ātman.
