SrI: SrImathE SatakOpAya nama: SrImathE rAmAnujAya nama: SrImath varavaramunayE nama:
yat tad agre viṣam iva
tat sukhaṁ sāttvikaṁ proktam
‘That is called Sātvika-Happiness, which at
first as venom is, but nectar in the end; —springing from ātma-knowing serenity.’
That Happiness, which by hard effort at the beginning of Yoga has to be achieved, and which by its singular nature has not yet been tasted; and therefore seems like venom, i.e., painful. But in the end, or when by the strength of practice, its singular nature is experienced, it is like nectar.
And this Happiness springs from ātma-knowing serenity.
The mind or the understanding which concerns itself with ātma is ātma-knowing mind.
Serenity means the calmness which comes to this mind when all other objects (save ātma) have been divorced from its contemplation. From this divorcement arises the experience of ātma, and this experience is the Happiness which is like nectar; and this is called Sātvika-Happiness.
