“Bhumi assumed the shape of a cow and presented herself before Lord Brahma with tears in her eyes. She was bereaved and was weeping just to invoke the Lord's compassion. She related the calamitous position of the earth, and after hearing this, Lord Brahma became much aggrieved, and he at once started for the ocean of milk, where Lord Vishnu resides.” (Krishna, The Supreme Personality of Godhead, Vol 1, Ch 1)
