On this path of liberation, the yoga of action, there is no loss of an undertaking once begun, as there is with farming and the like: an undertaking in the field of yoga is not of uncertain fruit. Nor is there, as with a course of medicine, any adverse result. Rather, even a little of this dharma, the dharma of yoga, once practised, protects from great fear, from the fear of transmigration, marked by birth, death and the rest. This understanding, told in Sāṅkhya and about to be told in yoga.
