that a knower of Brahman may perform his duties in any way is) an
injunction, like the holding (i.e. studying)". That is, the above text
is an injunction with reference to the pariṇiṣṭha devotees, allowing
them to act according to their will, just like the injunction, viz. that a
Brāhmaṇa is to be initiated in order that he may study the Veda ¹
Adhikaraṇa 2: The section entitled "A Mere
Eulogy". (Sūtras 21-22)
SŪTRA 21
"IF IT BE OBJECTED THAT (THE TEXTS ABOUT THE BEST ESSENCE
AND THE LIKE ARE MERE EULOGY, ON ACCOUNT OF TAKING (THEM
AS CONNECTED WITH PARTS OF SACRIFICES,) (THEN WE REPLY )
NO, ON ACCOUNT OF BEING NEW."
Vedānta-pārijāta-saurabha
If it be objected that texts like: "This is the best essence
among the essences" (Chānd. 1. 1.3 ²) and so on, are "mere eulogy"
of udgītha and the rest, the subsidiary parts of sacrificial acts, since
the best essence and the rest are taken as related to them,—(we reply.)
"No". This being not established before, here there is an injunction
with regard to the udgītha and the rest to be looked upon as the best
essence.
Vedānta-kaustubha
It has been established above that since in the text: "There are
three branches" (Chānd. 2.2.3, 1) and so on, the other stage of life is
mentioned as equal to the stage of a house-holder, the former is to
be adopted. Similarly, as the groups of texts about the best essence
are similar to the texts about the sacrificial ladle the sun and so on
which relate to the subsidiary parts of sacrificial acts, the former too
are subsidiary parts of such acts,—apprehending this objection, (the
author) is now disposing of it.
