Dhauti, basti, neti, laulikī, trāṭaka and kapālabhāti — these are called the six acts.

The classical list of cleansing practices, given here as a bare enumeration before each is described. Only two of the six — neti and trāṭaka — are commonly taught today without supervision, and even those have cautions.

This verse is the source of the word ṣaṭkarma, and the reason cleanliness (śauca) in the Sutras grows into a practical syllabus in the hatha texts.

The six acts are often marketed as detoxification. The texts describe them as clearing the passages the breath moves through — a plumbing metaphor, not a metabolic claim.
