Sūtra translation
Only when it is optional or only when there is neither compulsion to do nor fear of violation, the attainment of heaven is an accomplishment; otherwise it would be contradictory to (in- consistent with) (the notion or state of release and blessedness).
Only when the compulsion to do and liability to punishment for omission are absent, the state of being released, i.e., heavenly existence would be an end worth seeking and accomplishing; otherwise it would be no release at all. And the Brahmandapurana has the following to the same effect: “ Those that have crossed over all (misery) that is to be got over and have attained to the blessed existence by the grace of the Lord, sometimes perform acts ; sometimes they do not at all; but their very essence consisting of eternal wisdom and knowledge, they always meditate on the Lord of Lords; for they are neither in bondage nor in fear of omission and they do everything only of their own accord.”
