Translation:

Om the Ganges, Jamuna, Godavari, Sarasvati, Narmada, Sindhu and Kaveri, these waters (of the seven sacred rivers of the Indian Subcontinent) are brought together (in order to make the water sacred, a reflection of both the wonders of the external waters of Earth and the internal rivers, the nadis, of our spiritual bodies).

Listen to the mantra:

This mantra is used during our Kali Puja to bless water that is used during the ceremony. Use it to bless all water you may have for any ritual use, even in the daily karmic meditations of your spiritual life, such as when taking a bath. You may also wish to use it prior to drinking water to imbue it with sacred intention.

This mantra naturally draws us closer to our spiritual nature by charging the nadis, or internal rivers, of our pranic bodies.
