When the Yogi has seen all these wonderful powers, and rejected them, he reaches the goal

Verse 3.50

सत्त्वपुरुषान्यताख्यातिमात्रस्य सर्वभावाअधिष्ठातृत्वं सर्वज्ञातृत्वं च ॥५०॥

sattva-puruṣa-anyatā-khyātimātrasya sarva-bhāvā-adhiṣṭhātr‌tvaṁ sarva-jñātr‌tvaṁ ca ॥50॥

Only one who knows the difference between the illuminative intelligence and the purusha attains supreme knowledge of all that exists and all that manifests.

Verse 3.51

तद्वैराग्यादपि दोषबीजक्षये कैवल्यम् ॥५१॥

tad-vairāgyād-api doṣa-bīja-kṣaye kaivalyam ॥51॥

By giving up even these comes the destruction of the very seed of evil; he attains Kaivalya.

When we have conquered nature, and realised the difference between the Purusa and nature, that the Purusa is indestructible, pure and perfect, when the Yogi has realised this, then comes omnipotence and omniscience.

He attains aloneness, independence. Then that man is free. When he gives up even the ideas of omnipotence and omniscience, there will be entire rejection of enjoyment, of the temptations from celestial beings. When the Yogi has seen all these wonderful powers, and rejected them, he reaches the goal. What are all these powers? Simply manifestations. They are no better than dreams. Even omnipotence is a dream. It depends on the mind. So long as there is a mind it can be understood, but the goal is beyond even the mind.

From renunciation springs eternal emancipation, unalloyed purity. This is kaivalya. The self, now, has achieved absolute independence and abides in its own nature.
