Hindu spiritual literature from the Vedas, the Mahabharata and the Ramayana, to the eighteen Puranas mention the purity and glory of Mother Ganga, and several of these texts have elaborate hymns in her praise. Below are just a few of these passages:
Bhagavad Gita
“Living creatures are nourished by food, and food is nourished by rain; rain itself is the water of life, which comes from selfless worship and service.” – Bhagavad Gita 3:14
Upanishads
Puranas
“India is great, the Himalaya are great, but the region in the Himalayas where Ganga is born is especially great because that is the place where She [Ganga] exists in confluence with Narayana.” – Skanda Purana
“Even if thousands and thousands of sinners touch the dead bodies and bathe in thee [Ganga], all those will be destroyed when devotees will come and touch thee.” – The Devi Bhagavatam, Skanda IX
“Thousands of man’s sins get destroyed by the holy sight of the Ganges, and he becomes pure by the touch of the water of the Ganges, by consuming it, or just by pronouncing Ganga.” – Garuda Purana
“Mountains of sins accumulated by a sinner in the course of his millions of transmigrations on earth disappear at a mere touch of the sacred Ganga water. Cleansed will he be also, who even breathes some of the air moistened by the holy waters.” – Brahmavaivarta Purana
Mahabharata
“That end which a creature is capable of attaining by penances, by Brahmacharya, by sacrifices, or by practicing renunciation, one is sure to attain by only living by the side of Bhagirathi and bathing in her sacred waters.” – Mahabharata, Anusasana Parva, Chapter 27, Verse 26
“One may, by putting forth one’s best powers, count the stones that occur in the mountains of Meru or measure the waters that occur in the ocean, but one cannot count all the merits which belong to the waters of Ganga.” – Mahabharata, Anusasana Parva, Chapter 27, Verse 97
“Ganga always extends her unto those that are devoted to her with humbleness of heart. She unites those that are so devoted to her with every kind of happiness.” – Mahabharata, Anusasana Parva, Chapter 27, Verse 100
