Its flow becomes peaceful through repetition of the impression.

Tasya refers to nirodha parināma. Praśānta is peaceful, calmed. Vāhitā is flow. Saṃskāra is the latent impression.

When cessation is practiced repeatedly, its impressions strengthen. The flow of nirodha becomes increasingly natural and stable.

It is the principle of training: what is repeated is reinforced. Each moment of stillness leaves an imprint that facilitates the next moment of stillness.

At first, calm is fragile and brief. With sustained practice, the flow of tranquility becomes firmly established.

The saṃskāras of nirodha eventually overcome those of vyutthāna. The mind, which before naturally tended toward agitation, now naturally tends toward peace.

This is the mechanism by which meditation transforms the mind: not through repression but through patient cultivation of new impressions.
