In plain words
Even if all this is already understood, it still has to be said again — through what the scriptures of the ātman distill down to, and through practice: holding the mind on Hari, singing Hari.
Close to the Sanskrit
Although it is thus known, even so it must indeed be expounded — by the essences of the scriptures concerning the Self, by the practices of contemplating and singing of Hari.
