Devotional service on this highest, most excellent platform of lover and beloved, which had never been given by any previous incarnation or ācārya, was given by Caitanya Mahāprabhu. Therefore Kṛṣṇadāsa Kavirāja, quoting Śrīla Rūpa Gosvāmī, writes in the fourth verse of his book, "Lord Caitanya is Kṛṣṇa in a yellow complexion, and He is Śacīnandana, the son of mother Śacī. He is the most charitable personality because He came to deliver kṛṣṇa-prema, unalloyed love for Kṛṣṇa, to everyone. May you always keep Him in your hearts. It will be easy to understand Kṛṣṇa through Him."
