Chapter 3 · Verse 10
Karma Yoga
कर्मयोग
In plain words
You are being called to embrace selfless sacrifice as a way to thrive in this world. The Creator designed life so that your selfless actions, or karma, act like a wish-fulfilling cow. When you perform your duty, which is your dharma, for others, you naturally receive everything you need to prosper.
Translation
3.10 In the beginning the Lord of all beings, creating man along with the sacrifice, said: 'By this shall you prosper; this shall be the cow of plenty granting all your wants.'
Meaning
Prajapati is the Creator or Brahma. Kamadhuk is another name for the cow Kamadhenu. Kamadhenu is the cow of Indra from which everyone can milk whatever one desires. (Cf. VIII.4IX.2427X.25).
