Śrī Mādhavendra Purī was the first person in that disciplic succession to exhibit the symptoms of love of Godhead and the first to write a poem beginning with the words ayi dīna-dayārdra nātha, “O supremely merciful Personality of Godhead.” In that poem is the seed of Caitanya Mahāprabhu’s cultivation of love of Godhead.

CC Adi 9.10, Translation and Purport

All glories to Śrī Mādhavendra Purī, the storehouse of all devotional service unto Kṛṣṇa! He is a desire tree of devotional service, and it is in him that the seed of devotional service first fructified.

Śrī Mādhavendra Purī, also known as Śrī Mādhava Purī, belonged to the disciplic succession from Madhvācārya and was a greatly celebrated sannyāsī. Śrī Caitanya Mahāprabhu was the third disciplic descendant from Śrī Mādhavendra Purī. The process of worship in the disciplic succession of Madhvācārya was full of ritualistic ceremonies, with hardly a sign of love of Godhead. Śrī Mādhavendra Purī was the first person in that disciplic succession to exhibit the symptoms of love of Godhead and the first to write a poem beginning with the words ayi dīna-dayārdra nātha, “O supremely merciful Personality of Godhead.” In that poem is the seed of Caitanya Mahāprabhu’s cultivation of love of Godhead.
