Rapidly and vigorously to the lotus of the heart, then exhaling the prāṇa in the opposite direction, in the same manner.

This verse describes the rhythm of bhastrikā. Laghu (light/rapid) and vega (speed/vigor) characterize both inhalation and exhalation. Both phases are active and energetic, unlike kapālabhāti where only the exhalation is forced.

Hṛdayābja — “lotus of the heart” — indicates that the inhalation must be deep, filling the lungs to the heart region. The prāṇa does not remain superficially in the throat but penetrates deeply into the chest.

Pratilomaṃ — “in the opposite direction” — describes the exhalation that pushes air outward. Tadvad eva — “in exactly the same manner” — emphasizes that the exhalation must have the same speed and vigor as the inhalation. This equal rhythm distinguishes bhastrikā from kapālabhāti.
