Sri Caitanya-caritamrta

CC Madhya-lila

There are two processes by which one may execute this rāgānugā bhakti—external and internal. When self-realized, the advanced devotee externally remains like a neophyte and executes all the śāstric injunctions, especially those concerning hearing and chanting. But within his mind, in his original, purified, self-realized position, he serves Kṛṣṇa in Vṛndāvana in his particular way. He serves Kṛṣṇa twenty-four hours a day, all day and night.
