Bhagavad Gita Chapter 10, Verse 27
उच्चैःश्रवसमश्वानां विद्धि माममृतोद्भवम् | ऐरावतं गजेन्द्राणां नराणां च नराधिपम् ||
uccaiḥśravasam aśvānāṁ viddhi mām amṛtodbhavam airāvataṁ gajendrāṇāṁ narāṇāṁ ca narādhipam
Among horses, know Me to be Ucchaihshrava, born from the churning of the ocean of nectar; among lordly elephants, I am Airavata; and among humans, I am the king.
Krishna continues enumerating manifestations in animals and humans. 'Uccaiḥśravasam aśvānāṁ viddhi mām amṛtodbhavam'—among horses, know Me to be Ucchaihshrava, born from the churning of the ocean of nectar. Ucchaihshrava is the divine horse that emerged from the churning of the ocean. 'Airāvataṁ gajendrāṇām'—among lordly elephants, I am Airavata. Airavata is Indra's divine elephant. 'Narāṇāṁ ca narādhipam'—among humans, I am the king. This verse shows Krishna as the best in each category: the divine horse among horses, the divine elephant among elephants, and the king among humans. Each represents excellence in its category—the source manifesting as the best.
