A king drawn out of a tyrant's body who made the earth level and fruitful — and gave the earth her name, Prithvi.
Appears in
Prithu milks the earth — Skandha 4, adhyayas 15-23 — Born from a dead tyrant's arm, the first consecrated king chases the earth as a cow until she agrees to give her milk.
Embodies
The descents of the Lord — Boar, man-lion, dwarf and fish: the Lord comes down in whatever form the age needs, and Krishna is the Lord himself (1.3.28).
Devotion as the highest dharma — The Bhagavatam's own thesis (1.2.6): the highest dharma is devotion with no motive, which nothing can interrupt.
