Origin of Ganges

Ganges originates from the confluence of Alaknanda and Bhagirathi at Devprayag, a municipality in Tehri Garhwal district in the North Western state of Uttarakhand. Alaknanda rises in the foot of Satopanth glacier in Uttarakhand, while Bhagirathi originates at Gaumukh (3892 mtrs) at the foot of Gangotri glacier in Garhwal. On account of being longer than Bhagirathi and also having more discharge, Alaknanda is considered the source stream of Ganga, but Bhagirathi holds much religious importance for Hindus and is more revered.

The name ‘Devparyaga’ has a special meaning in Sanskrit and it holds much religious significance for Hindus. ‘Dev’ is a reference to God, and ‘Prayag’in Sanskrit means ‘confluence’. ‘Devprayag’ thus becomes the place for the confluence of Gods, or the place where Gods meet, to be more specific. Devprayag has derived its name from sage Dev Sharma who lived his devotional life there. Devprayag has much religious importance for Hindus and is a centre place for many religious fests and activities.

Among the two tributaries of Ganges, the Bhagirathi is considered as the sacred and its bank at Devprayag is marked with many temples and religious activities.

Before reaching Varanasi the Ganges meets Yamuna at Prayag- Allahabad, which is also a place of religious significance for the Hindus and a venue for Mahakumbh organized every 12 years.

The Ganges flows east from Allahabad till Bhagalpur in Bihar, where it starts flowing southeast and at Pakur in Jharkhand it branches out into two distributaries- Hooghly and Padma. The Hooghly also known as Bhagirathi- Hooghly passes through the towns of Kolkata and Howrah before emptying into the Bay of Bengal at Sagar Islands. The main distributary of Ganges is called Padma in West Bengal and traverses through a course of 120 km before emptying into the Bay of Bengal.

Mythological Beliefs

Hindu religion personifies the Ganges as a goddess ‘Ganga’, and Hindu believe that Ganga has the power to purify the sins of anyone bathing in its holy water on certain occasions. Many too believe that bathing anytime in the holy waters of Ganges wiil purify their sins and will help them attain salvation. The banks of Ganges are a site of much religious activity and are marked by a number of temples and pilgrimage centers. It is believed by Hindus that immersing the ashes of the dead in the holy water of Ganga will open their doors to Heaven. The Ganges is also known as ‘Vishnupadi’-emerging from the lotus feet of Lord Vishnu. Ganga is also believed to be the daughter of Himvana (Mountain god) and Mena and therefore the sister of Parvati.

There is an interesting mythological story narrated by Hindu religion about the appearance of Ganges on earth. The story starts with a king named Sagara, who magically obtained 60000 sons and performed an Ashvamegha Yagya, which is a horse sacrifice ritual, to please Gods. His horse was stolen by Indra, who was jealous of his achievements. Infuriated by the missing horse he sends his sons to look for it. His sons found the horse near a meditating sage Kapila, who had been meditating there for years. Mistakenly thinking of Kapila as the one who stole the horse, the sons started insulting him. On listening to the commotion, Kapila opened his eyes after many years, burning all the sons of Sagara to death by the glare of his eyes. Devoid of their final rites the souls of Sagara’s sons were left roaming in the valleys.

Bhagiratha, a descendant of Sagar came to know about the plight of Sagara’s sons and pledged to get their souls released to heaven by bringing Ganga for cleaning their souls. He started praying to Brahma for bringing Ganga on earth so that the souls of Sagara’s sons can be purified. Brahma agreed and ordered Ganga to flow down to earth in order to purify the souls of the sons of Sagara and others. An egotistic Ganga took it as an insult and started pouring down on earth with tremendous rage and fury resulting in huge destruction.  Fearing the destruction, Bhagiratha started praying Shiva for breking Ganga’s descent.

Consequently Shiva obliged by tying Ganga in his head hairs and letting her out in small streams, to subdue her rage and fury and make her more productive and a mean to attain purification and salvation.
