उच्चैःश्रवसमश्वानां विद्धि माममृतोद्भवम्। ऐरावतं गजेन्द्राणां नराणां च नराधिपम् ॥

uchchaiḥśhravasam aśhvānāṁ viddhi mām amṛitodbhavam airāvataṁ gajendrāṇāṁ narāṇāṁ cha narādhipam

Uchchaishravas of horses know me, nectar-born; Airâvata of lordly elephants, and of men the Monarch.

In plain words: Krishna says that among horses He is Uchchaishravas, the heavenly horse born when the ocean was churned for nectar. Among royal elephants, He is Airavata. Among people, He is the king.
