Sat-darshana Bhashya (translation)

Verse 29.

सत्या स्थिति हमुदेति यत्र
तच्चोदयस्थानगवेषणेन ।
विना न नश्यद्यदि तन्न नश्येत्
स्वात्मैक्यरूपा कथमस्तु निष्ठा ।

That is the Real state, where the ego lives not. Its birth-place sought, the ego dissolves. Nowise else can one attain The supreme state of one’s own Self.

There is no formation of the ego in the state of supreme reality of the Self. This is a truth that survives the ego, even as it is always present behind the appearance of the ego. Though it is present in all states, even during the persistence of the ego, its presence is not felt in egoistic existence. When the ego-self feels the pressure of a need to know its own source, or feeling the urge of a supreme impulse gets into a movement of serious quest for its origin, it loses itself. Loss of ego results in the realisation of the oneness of the ego-self with the real ’I’ the deeper self in that exalted settled state called nistha (vide 32nd verse).

Having pointed out many methods of quest, the Shastra now enjoins a different method, that of plunging in. This is really the essence of Hridaya Vidya, the mystic discipline that leads to the central seat of the Purusha, the Spirit in man.
