Having then wedded, agreeably to law, all the princesses, the sage took them home to his habitation, where he employed the chief of architects, Viśwakarman, equal in taste and skill to Brahmá himself, to construct separate palaces for each of his wives: he ordered him to provide each building with elegant couches and seats and furniture, and to attach to them gardens and groves, with reservoirs of water, where the wild-duck and the swan should sport amidst beds of lotus flowers. The divine artist obeyed his injunctions, and constructed splendid apartments for the wives of the Rishi; in which by command of Saubhari, the inexhaustible and divine treasure called Nanda took up his permanent abode, and the princesses entertained all their guests and dependants with abundant viands of every description and the choicest quality.
