The Blessed Lord said: I shall declare to you again the supreme knowledge among all knowledges, knowing which all sages have attained supreme perfection from here.

This is “again” (bhūyaḥ) because knowledge has been taught before, but now Kṛṣṇa presents the uttama — supreme — knowledge: the guṇa-vidyā or science of the three qualities.

The parāṃ siddhim — supreme perfection — is liberation from the cycle of birth and death. This is not magical power but freedom from all limitation.

Munayaḥ — sages — indicates that this teaching has been verified by realized beings throughout history, not merely theoretical philosophy.
