With the air controlled, the mind is controlled;with the bindu controlled, he is free of disease.Having stabilized in the control of the mind, then the bindu stabilizes.

This verse presents the triadic interconnection between vāyu, manas and bindu.Vāyur baddho mano baddham — when the air is controlled (baddha), the mind is controlled.This is the fundamental premise of haṭha yoga: breath and mind are inextricably linked.

Bindur baddho nirāmayaḥ — with the bindu controlled, there is absence of disease.Bindu, the vital essence, when preserved and sublimed, generates perfect health.Its loss or dispersion causes physical deterioration.

The second part presents the reverse circuit: manobandhe sthiro bhūtvā — having stabilized in control of the mind — binduṃ sthiraṃ bhavet — the bindu stabilizes.The Bihar School emphasizes this reciprocity: you can work from the body to the mind (via prāṇāyāma) or from the mind to the body (via meditation).Both routes are valid and mutually reinforcing.
