Only for one who has knowledge of the distinction between sattva and puruṣa arise supremacy over all states and omniscience.

Sattva is the pure mind. Puruṣa is the Self. Anyatā is difference. Khyāti is discriminative knowledge. Sarvabhāva is all states. Adhiṣṭhātṛtva is supremacy, lordship. Sarvajñātṛtva is omniscience.

This sutra elevates the discussion from 3.35. One who truly distinguishes between the purest mind (sattva) and the witness Self (puruṣa) obtains:

Sarvabhāvādhiṣṭhātṛtva: lordship over all states of existence. Nothing in prakṛti can dominate them.

Sarvajñātṛtva: knowledge of everything. There is nothing they cannot know if they direct attention there.

It is the pinnacle of siddhis. But note: these powers arise from discriminative knowledge, not from practicing powers.

The yogī who discriminates correctly obtains total mastery as a byproduct. They do not seek it; it is given.

It is the paradox of the path: by renouncing power, all power is obtained.
