Knowing the truth through the search for nāda, he proclaims himself rāja yoga.The light of lights resides in the body;the mental is beyond the mind.

This verse connects nāda yoga with rāja yoga.Nādānveṣaṇa — the search for nāda, the inquiry into the inner sound — is a path to tattvajña — the knowledge of truth.This process is proclaimed (prakīrtita) as rāja yoga, the real yoga.

Jyotiṣāṃ jyotiḥ — the light of lights — a Vedic phrase that describes the supreme consciousness as that which illuminates everything else.This light is not in a distant sky but dehastha — residing in the body.Haṭha yoga insists on the sacredness of the body as a temple of the divine.

Mānaso manasaḥ paraḥ — the mental (or that which belongs to the mind) is beyond the mind.Paradox that points towards self-transcendence: the mind can know that which transcends it.The Bihar School interprets this as indication of the witness (sākṣin) — the consciousness that observes the mind without being affected by its fluctuations.
