। ॥ ३६१ ॥
In plain words
So: if you want out of the bondage of saṃsāra, unyoke the mind from rajas and tamas and everything the two of them produce — and then, with real effort, always, make that mind sattva made wholly clear, and make it dear to you.
Close to the Sanskrit
Therefore, for release from the bondage of worldly existence, the seeker of liberation, having disjoined the mind from rajas and tamas and from their effects, should always indeed, with effort, make it of wholly purified sattva and dear.
