My dear friend, where is Kṛṣṇa, who is like the moon rising from the ocean of Mahārāja Nanda’s dynasty? Where is Kṛṣṇa, His head decorated with a peacock feather? Where is He? Where is Kṛṣṇa, whose flute produces such a deep sound? Oh, where is Kṛṣṇa, whose bodily luster is like the luster of the blue indranīla jewel? Where is Kṛṣṇa, who is so expert in rāsa dancing? Oh, where is He, who can save My life? Kindly tell Me where to find Kṛṣṇa, the treasure of My life and best of My friends. Feeling separation from Him, I hereby condemn Providence, the shaper of My destiny.
