85-6): "Amid all these acts the knowledge of self, _[=a]tm[=a],_ is the highest, for it produces immortality.

Amid all these acts the one most productive of happiness, both after death and in this life, is the Vedic ceremony." Knowledge gives real immortality; rites give temporary bliss.

The Upanishads teach that the latter is lower than the former, but each answers the question.

There were two answers, and Manu gives both.
That is the secret of many discrepancies in Hindu rules.

The law-giver cannot admit absolutely and once for all that the Vedic ceremony is of no abiding use, as it can be of no use to one that accepts the higher teaching.
