sahasra-śīrṣatāṁ kecit kecid vaikuṇṭha-nāthatām brūyuḥ kṛṣṇasya munayas tat-tad-vṛtty-anugāminaḥ (Laghu-bhagavatamrta 5.383)

"According to the intimate relationships between Sri Krsna, the primeval Lord, and His devotees, the Puranas describe Him by various names. Sometimes He is called Narayana; sometimes Upendra (Vamana), the younger brother of Indra, King of heaven; and sometimes Ksirodakasayi Visnu. Sometimes He is called the thousand-hooded Sesa Naga and sometimes the Lord of Vaikuntha."
