Śaṅkarācārya's commentary

In this Yoga (karma-yoga) there is no loss of effort, as in agriculture — where a season's labour may yield nothing — and no contrary effect, as in medicine improperly given. Whatever is begun here, however small, is not wasted. Even a little of this devotion (dharma) delivers one from the great fear — the fear of saṃsāra, of birth and death.
