Kṛṣṇa, the Supreme Personality of Godhead, has no material body, yet He appears as a human being. For how many years did He live with the descendants of Vṛṣṇi? How many wives did He marry, and for how many years did He live in Dvārakā?
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
देहं मानुषमाश्रित्य कति वर्षाणि वृष्णिभिः । यदुपुर्यां सहावात्सीत्पत्न्यः कत्यभवन् प्रभोः
dehaṃ mānuṣamāśritya kati varṣāṇi vṛṣṇibhiḥ | yadupuryāṃ sahāvātsītpatnyaḥ katyabhavan prabhoḥ
