When the impressions of emergence are overcome and those of cessation appear, the mind becomes associated with the moment of nirodha: this is the transformation of cessation.

Vyutthāna is emergence, the active and scattered mind. Nirodha is cessation, restriction. Saṃskāra are latent impressions. Abhibhava is overcoming. Prādurbhāva is manifestation.

This sutra begins a technical section on parināmas, the transformations of the mind.

The mind oscillates between two states: vyutthāna (extroversion, activity) and nirodha (interiorization, stillness). Each state leaves impressions.

Nirodha parināma occurs when impressions of activity are gradually overcome by those of stillness. It is like a seesaw beginning to tilt toward silence.

It is not that the mind empties suddenly. It is a gradual process where moments of nirodha become more frequent and those of vyutthāna less dominant.

This parināma is the foundation of the other two that will be described.
