"The deities said, 'Our wishes, O holy one, have been crowned with fruition. We shall perform our sacrifice even here with large Dakshina. Let, however, the Munis always adore the piece of earth. Then there came to that place Agastya and Kanwa and Bhrigu and Atri and Vrishakapi, and Asita and Devala. The high-souled deities then, O thou of unfading glory, performed their sacrifice. Those foremost of gods concluded it in due time. Having completed that sacrifice of theirs on the breast of that foremost of mountains. Himavat, the deities attached to the gift of earth a sixth part of the merit arising from their sacrifice. The man who makes a gift of even a span of earth (unto a Brahmana) with reverence and faith, has never to languish under any difficulty and has never to meet with any calamity. By making a gift of a house that keeps out cold, wind, and sun, and that stand upon a piece of clean land, the giver attains to the region of the deities and does not fall down even when his merit becomes exhausted. By making a gift of a residential house, the giver, possessed of wisdom, lives, O king, in happiness in the company of Sakra. Such a person receives great honours in heaven.
