यत्तदग्रे विषमिव परिणामेऽमृतोपमम्।
तत्सुखं सात्त्विकं प्रोक्तमात्मबुद्धिप्रसादजम्।।18.37।।
18.37 That which is like poison at first but in the end like nectar that happiness is declared to be Sattvic, born of the purity of ones own mind due to Self-realisation.
18.37 Yat, that joy which is; iva, like; visam, poison, a source of pain; agre, in the beginning-when it first comes in the early stages of (acisition) of knowledge, detachment, meditation and absorption, since they involve great struggle; but amrtopamam, comparable to nectar; pariname, in the end, when it arises from the maturity of knowledge, detachment, etc.; and which atma-buddhi-prasadajam, arises from the purity (prasada), trasparence like water, of ones intellect (atma-buddhi); tat, that; sukham, joy; is proktam, spoken of, by the learned ones ;as sattvikam, born of sattva. Or, the phrase atma-buddhi-prasadajam may mean arising from the high degree of clearness of that atma-buddhi (knowledge of or connected with the Self); therefore it is born of sattva.
