Without doing any deep research on the subject, these are two quotes by Jawaharlal Nehru pertaining to the River Ganga :

The Ganga, especially, is the river of India, beloved of her

people, round which are intertwined her memories, her hopes

and fears, her songs of triumph, her victories and her

defeats. She has been a symbol of India's age-long culture

and civilization, ever changing, ever flowing, and yet ever

the same Ganga

- Pandit Jawahar Lal Nehru

The Ganga to me is the symbol of India’s memorable past which has been flowing into the present and continues to flow towards the ocean of the future.

-Pandit Jawahar Lal Nehru

The Holy River of India

And finally this :

Rahul quoted Nehru as saying, "I have been attached to the Ganga and the Jamuna rivers in Allahabad ever since my childhood and, as I have grown older, this attachment has also grown. The Ganga, especially, is the river of India, beloved of her people. She has been a symbol of India's culture and civilization, ever-changing, ever-flowing and ever the same Ganga. She reminds me of the snow-covered peaks and the deep valleys of the Himalayas..."
