पवनः पवतामस्मि रामः शस्त्रभृतामहम्। झषाणां मकरश्चास्मि स्रोतसामस्मि जाह्नवी ॥

pavanaḥ pavatām asmi rāmaḥ śhastra-bhṛitām aham jhaṣhāṇāṁ makaraśh chāsmi srotasām asmi jāhnavī

Of purifiers I am the wind; Rama of warriors I; and I am Makara of fishes; of streams the Gangâ am I.

In plain words: Krishna says that among things that make clean, he is the wind. Among warriors he is Rama, the hero king. Among sea creatures he is the Makara, a great sea animal, and among rivers he is the Ganga, India's holy river.
