Longing is now defined: Longing means “having intense greed for attaining service to the Lord.”
Purport
Eagerness for Achieving the Desired Success When one is sufficiently eager to achieve success in devotional service, that eagerness is called samutkaṇṭhā. This means “complete eagerness.” Actually this eagerness is the price for achieving success in Kṛṣṇa consciousness. Everything has some value, and one has to pay the value before obtaining or possessing it. It is stated in the Vedic literature that to purchase the most valuable thing, Kṛṣṇa consciousness, one has to develop intense eagerness for achieving success.
