। ॥ १५ ॥
In plain words
Samādhi is possible — the mind held back from everything — and the yogins hold it dearest. If you cannot do that, still the mind for one moment: the one who trusts finds the ātman's own brahman-nature.
Close to the Sanskrit
Samādhi, possible through the restraint of everything, is dear to yogins; in the inability for that, having restrained [the mind] for a moment, the faith-filled one [gains] the brahman-ness of the self.
