“ ‘The devotees now present are constantly thinking of the Supreme Lord and are therefore highly advanced. This work named Vidagdha-mādhava depicts the characteristic pastimes of Lord Kṛṣṇa with decorations of poetic ornaments. And the inner grounds of the forest of Vṛndāvana provide a suitable platform for the dancing of Kṛṣṇa with the gopīs. Therefore I think that the pious activities of persons like us, who have tried to advance in devotional service, have now attained maturity.’
This is verse 8 of the first act of the Vidagdha-mādhava.
