Their active manifestations must be eliminated through meditation.

While the previous sutra dealt with the subtle kleśas, this one addresses the vṛttis, the active mental fluctuations that arise from the afflictions.

Dhyāna (meditation) is the antidote for the gross manifestations of the kleśas. When aversion, attachment, or fear arise as active thoughts, meditation calms them.

There is a progression: first we use dhyāna to quiet the obvious disturbances; then, with a clearer mind, we can access the subtle roots through pratiprasava.

This dual approach—dhyāna for the gross, pratiprasava for the subtle—shows the sophistication of Patañjali’s method.
