Among purifiers I am the wind, and among wielders of weapons I am Rama. Among fish I am the makara, and among flowing rivers I am the Jahnavi (the Ganga).
Explanation
Krishna continues listing his "manifestations" (vibhūti), the finest example in each category, to help Arjuna see the divine in the world. Here he names the wind (pavana), Rama (the ideal warrior-king), the makara (a legendary sea creature, often read as a crocodile or shark), and the Ganga, called Jahnavi. The word pavatām can mean "purifiers" or "movers/swift ones"; both readings are found among commentators, and the verse works with either.
