āvṛtaṁ jñānam etena
āvṛtam — covered; jñānam — pure consciousness; etena — by this; jñāninaḥ — of the knower; nitya-vairiṇā — by the eternal enemy; kāma-rūpeṇa — in the form of lust; kaunteya — O son of Kuntī; duṣpūreṇa — never to be satisfied; analena — by the fire; ca — also.
Thus the wise living entity’s pure consciousness becomes covered by his eternal enemy in the form of lust, which is never satisfied and which burns like fire.
