। ॥ ३०९ ॥
In plain words
So now, draw your attention back from 'I' and everything it drags along. Let go of every attachment, since you have already found what matters most. Simply rest - quietly, wholly, with nothing left dividing you from it - in Brahman, tasting the bliss that is your own Self.
Close to the Sanskrit
Therefore, having withdrawn the mental function from 'I' and the rest, having abandoned attachment through attaining the supreme goal, remain silent, through the experience of the bliss of your own Self, wholly, without duality, in Brahman.
