In the pūrva rāga-(beginnings of love) condition we can see that the youthful spiritual
Cupid of Vṛndāvana does not like anyone else but Rādhārāṇī. Thinking that they are all Rādhā, He embraces golden Jhintī-flowers, landlotuses and so on, telling His brāhmaṇa-friend Madhumaṅgala: “O friend! Won’t you show Me this Rādhā?” Madhumaṅgala writes Rādhā’s name on a lotuspetal. Seeing the syllables of Her name, Kṛṣṇa is satisfied and says: “These syllables are My very life!”

Such love He could not find anywhere in this world! That’s why the personification of intense bliss (Kṛṣṇa) is so mad after Śrīmatī!

My Gurudeva quoted this from Śrīla Rūpa Gosvāmī’s Vidagdha Mādhava, Act V (tika to Vilapa Kusumanjali verse 21)
