। ॥ ३८० ॥
In plain words
Stop dwelling on the non-Self — that thinking is a taint, and it is what causes every sorrow you have. Turn instead to the Self, whose very nature is bliss, because that is what actually sets you free.
Close to the Sanskrit
Having abandoned thought of the non-Self, which is a taint, the cause of sorrow, meditate on the Self, whose nature is bliss, which is the cause of liberation.
