Śrī Caitanya Mahāprabhu said, “‘Alas, what shall I do? To whom shall I speak? Let whatever I have done in hopes of meeting Kṛṣṇa be finished now. Please say something auspicious, but do not speak about Kṛṣṇa. Alas, Kṛṣṇa is lying within My heart like Cupid; therefore how can I possibly give up talking of Him? I cannot forget Kṛṣṇa, whose smile is sweeter than sweetness itself and who gives pleasure to My mind and eyes. Alas, My great thirst for Kṛṣṇa is increasing moment by moment.'".
