Vishwakarma, AKA Tvashta, is the architect of the gods. He built, among other things, Indra's city of Amaravati, Krishna's city of Dwaraka, and Ravana's city of Lanka. His daughter Sanjana married Surya the sun god, as I discuss here, and his son Trisiras temporarily served as the guru of the gods, as I discuss here and here. And he's responsible for the creation of Vritrasura, a famous demon that Indra is known for defeating.
But I'm interested in another story involving Vishwakarma. This excerpt from the Aitareya Brahmana of the Rig Veda describes the benefits that various kings have derived from performing the Rajasuya Yagna, and here is what it says about Vishwakarma:
With this great anointing of Indra Kashyapa anointed Vishvakarman Bhauvana. Therefore Vishvakarman Bhauvana went round the Earth completely, conquering on every side, and offered the horse in sacrifice. The earth sang, they tell:
'No man whatsoever ought to give me,
O Vishvakarman Bhauvana, thou hast been fain to give me;
I shall plunge into the middle of the water;
Vain was this thy compact with Kashyapa.'
(Bhauvana means son of the Earth.) This chapter of the Shatapatha Brahmana of the Yajur Veda says the same thing:
Visvakarman Bhauvana once performed this sacrifice, and having performed it he overpassed all beings, and became everything here; and verily he who, knowing this, performs the Sarvamedha, or who even knows this, overpasses all beings, and becomes everything here.
It was Kasyapa who officiated in his sacrifice, and it was concerning this that the Earth also sang the stanza;--'No mortal must give me away; thou wast foolish, Visvakarman Bhauvana: she (the earth) will sink into the midst of the water; vain is this thy promise unto Kasyapa.'
So it seems that Vishwakarma, as part of a Sarvamedha Yagna, gave away all his possessions, which included the Earth itself, to the sage Kashyapa who had conducted the Yagna. But Bhumidevi the goddess of the Earth told him that no one was allowed to give her away, so she said she would submerge herself into the water so that Vishwakarma wouldn't fulfill his promise to Kashyapa.
My question is, what ultimately happened? Did the Earth get submerged, and if so how did emerge from the water? Was this similar to the occasion that Vishnu's incarnation Varaha retrieved the Earth from the water?
Are there any other scriptures that discuss this story?
