Bhagavad Gita · 10.27

उच्चैःश्रवसमश्वानां विद्धि माममृतोद्भवम्।ऐरावतं गजेन्द्राणां नराणां च नराधिपम्॥

uchchaiḥśhravasam aśhvānāṁ viddhi mām amṛitodbhavam airāvataṁ gajendrāṇāṁ narāṇāṁ cha narādhipam

Among horses, know me to be Uchchaihshrava, born from the churning of the ocean of nectar. Among elephants, I am Airavata. Among humans, I am the king.
