Purport: 

Śrīla Śrīdhara Svāmī points out that as Uddhava wandered about Vṛndāvana, he reminded Vraja’s residents of Kṛṣṇa by asking them questions about the pastimes the Lord had performed in each of these places, namely the rivers, forests, mountains and valleys. Thus Uddhava himself enjoyed great transcendental bliss in their association.
