Slokam 6

Having released mother natures bounties, the Paramathma encourages the devas to enjoy the bounties. One of the eternal sources of unlimited food cited in Srimad Bhagavatham is the celestial cow Surabhi.  Sage Vasishta has the possession of surabhi. He entertains Visvamitra’s army with the bounties created by Surabhi. Viswmitra immediately wants take Surabhi with him.  A battle ensues that becomes very destructive. 

The analogy in this slokam is that Prithu was able to milk the bounties from mother earth as one would milk surabhi.

May we always remain dharmic so that mother earth does not withdraw her bounties from us.
