What is the name of the hymn in the Rig Veda that is entirely dedicated to rivers?

Show answer

Nadistuti Sukta

Step 1: Section 5.2 of the chapter discusses the importance of rivers in Vedic texts. Step 2: The text specifically mentions: 'The Rig Veda dedicates an entire hymn to the rivers. It is called the Nadistuti Sukta.' Step 3: 'Nadi' means river and 'stuti' means praise or hymn in Sanskrit, making this name meaningful. Step 4: The Prithvi Sukta is a hymn to Mother Earth found in the Atharva Veda. The Shantipath is the peace prayer from the Yajur Veda. 'Agni Sukta' is not a hymn mentioned in the chapter. Therefore, 'Nadistuti Sukta' is correct.
