As cities are constructed in the modern age with great engineering and architectural craftsmanship, so in days gone by there were neighborhoods called ṛṣi-kulas, where great saintly persons resided. In India there are still many magnificent places for spiritual understanding; there are many ṛṣis and saintly persons living in nice cottages on the banks of the Ganges and Yamunā for purposes of spiritual cultivation. While passing through the ṛṣi-kulas even the royal members were very much satisfied with the beauty of the cottages and hermitages. It is stated here, paśyann āśrama-sampadaḥ. The great sages had no skyscrapers, but the hermitages were so beautiful that even the King was very much pleased at the sight.
