Śaṅkarācārya's commentary

It is stainless like a pebble-stone, and therefore lucid and healthy. Sattva binds the Self by making Him think 'I am happy': it binds Him by causing in Him attachment to happiness, by bringing about a union of the subject (the Self) with the object (happiness). It makes Him think, "Happiness has accrued to me." This attachment to happiness is an illusion; it is avidyā. An attribute of the object cannot indeed belong to the subject. Thus it is through avidyā alone — which forms an attribute of the Self as the non-discrimination between the object and the subject — that Sattva causes the Self to be attached as it were to happiness which is not His own. Similarly, Sattva binds the Self by attachment to knowledge. 'Knowledge' here must be an attribute of the antaḥ-karaṇa — of the Kṣetra, of the Object — not of the Self; for if it were an attribute of the Self, it cannot be an attachment and cannot be a bondage. Attachment to knowledge arises in the same way that attachment to happiness arises.
