Yoga Sutras of Patanjali · 3.54

तारकं सर्वविषयं सर्वथाविषयमक्रमं चेति विवेकजं ज्ञानम्॥५४॥

tārakaṁ sarva-viṣayaṁ sarvathā-viṣayam akramaṁ ceti vivekajaṁ jñānam

The discriminative knowledge that is born of viveka — saving, embracing all objects and all conditions, instantaneous and not bound by sequence — is the supreme knowledge.
