Śaṅkaraon Brahma Sūtra 3.4.25

The expression ‘ For this very same reason ’ must be viewed as taking up SCitra III, 4, 1, because thus a satisfactory sense is established. For this very same reason, i.e. because knowledge subserves the purpose of man, the lighting of the sacrificial fire and similar works which are enjoined on the different d^ramas are not to be observed, since man’s purpose is effected through knowledge. The Sutrakara thus sums up the result of the first adhikara;/a, intending to make some further remarks.
