Being held together by cause, effect, support, and object, when these disappear, those also disappear.

This crucial sutra reveals how to dissolve vāsanās. Four factors keep them alive:

Hetu (cause): afflictions like avidyā that generate new impressions. Phala (fruit): the expectation of results that motivates action. Āśraya (support): the mind that stores impressions. Ālambana (object): external objects that stimulate latent tendencies.

When these four supports weaken or are eliminated, vāsanās lose their foundation and dissolve naturally.

Yogic practice works on all fronts: discernment eliminates causes, detachment neutralizes expectation of fruits, mental purification transforms the support, and withdrawal of senses reduces object stimulation.

It is not about suppressing impressions but eliminating conditions that feed them. Without fuel, the fire extinguishes itself.
