So the whole substance is creamed. You should take advantage of this. And don't indulge in much unnecessary talks. Time should be very properly utilized.

Nāma-gāne sadā ruci (CC Madhya 23.32): attachment for chanting always. Prītis tad-vasati sthale (CC Madhya 23.18-19): and attraction or attachment for living in the temple, vasati, where Kṛṣṇa lives. Kṛṣṇa lives everywhere, but specifically, to give us chance to meet, He lives in the temple or in places like Vṛndāvana. So prītis tad-vasati sthale: one should be enhanced in attachment for living where Kṛṣṇa is living. Prītis tad . . . nāma-gāne sadā ruci: and taste for singing always the holy name. These are development.
