Nadistuti sukta

The Nadistuti sukta (Sanskrit: नदिस्तुति सूक्त), "hymn of praise of rivers", is hymn 10.75 of the Rigveda.
It is important for the reconstruction of the geography of the Vedic civilization. Sindhu (the Indus) is addressed as the mightiest of rivers and addressed specifically in verses 1, 2, 7, 8 and 9 contrary to the mighty river of Sarasvati in the old books of 6, 3, and 7.
In verse 5, the rishi enumerates ten rivers, beginning with the Ganga and moving westwards: O Ganga, Yamuna, Sarasvati, Shutudri (Sutlej), Parushni (Iravati, Ravi), follow my praise! O Asikni (Chenab) Marudvridha, Vitasta (Jhelum), with the Arjikiya (Haro) and Sushoma (Sohan), listen!
Verse 6 adds northwestern rivers (tributaries of the Indus flowing through Afghanistan and north-western Pakistan),
"First thou goest united with the Trishtama on this journey, with the Susartu, the Rasa, and the Sveti, O Sindhu with the Kubha (Kophen, Cabul river) to the Gomoti (Gomal), with the Mehatnu to the Krumu ( Kurum) with whom thou proceedest together."
Griffith translates: "First united with the Trishtama in order to flow, with the Susartu and Rasa, and with this Svetya (you flow), O Sindhu (Indus) with the Kubha (Kabul R.) to the Gomati (Gomal), with the Mehatnu to the Krumu (Kurram), with whom you rush together on the same chariot."
More recent interpretations take the arrangement to corresponds to the eastward expansion of the Vedic culture. Recent linguistic reconstruction suggests that Book 6 is one of the earliest of the Rigveda, while book 10 is one of the youngest, so that it would appear that the Ganges still fell within the area of Vedic culture before the codification of the Rigveda.[citation needed] [original research?]
Talageri : In the Nadī Sūkta, the Indus alone is described in verses 1-4 and 7-9. And verse 5 refers to all the independent eastern rivers and the eastern tributaries of the Indus, while verse 6 refers to the western tributaries of the Indus clubbed together along with the Indus itself, which is again named in this verse, since all these western tributaries became known to the Vedic people only after they had crossed the Indus and are therefore part and parcel of the Indus itself to them, unlike its eastern tributaries which (like the independent eastern rivers) were or had become known to them before they came across the actual Indus river itself.[1]
