CC Madhya 2.79
īśvare se — ki ihā vismaya
tāhe mukhya-rasāśraya, ha-iyāchena mahāśaya,
tāte haya sarva-bhāvodaya
līlā-śuka — Bilvamaṅgala Ṭhākura; martya-jana — a person of this world; tāṅra — of him; haya — there is; bhāva-udgama — manifestation of different ecstasies; īśvare — in the Supreme Lord; se — that; ki — what; ihā — here; vismaya — astonishing; tāhe — in that; mukhya — chief; rasa-āśraya — mellows; ha-iyāchena — has become; mahā-āśaya — the great personality Śrī Caitanya Mahāprabhu; tāte — therefore; haya — there is; sarva-bhāva-udaya — a manifestation of all ecstasies.
Līlāśuka [Bilvamaṅgala Ṭhākura] was an ordinary human being, yet he developed many ecstatic symptoms in his body. What, then, is so astonishing about these symptoms’ being manifest in the body of the Supreme Personality of Godhead? In the ecstatic mood of conjugal love, Śrī Caitanya Mahāprabhu was on the highest platform; therefore, all the exuberant ecstasies were naturally visible in His body.
Līlāśuka is Bilvamaṅgala Ṭhākura Gosvāmī. He was a South Indian, a brāhmaṇa, and his former name was Śilhaṇa Miśra. When he was a householder, he became attracted to a prostitute named Cintāmaṇi, but eventually he took her advice and became renounced. Thus he wrote a book named Śānti-śataka, and later, by the mercy of Lord Kṛṣṇa and the Vaiṣṇavas, he became a great devotee. Thus he became famous as Bilvamaṅgala Ṭhākura Gosvāmī. On that elevated platform he wrote a book named Kṛṣṇa-karṇāmṛta, which is very famous amongst Vaiṣṇavas. Since he exhibited so many ecstatic symptoms, people used to call him Līlāśuka.
