Nag-Panchami is an important all-India festival and is celebrated on the fifth day of the moonlit-fortnight in the month of Shravan (July /August). This is the time when serpents invariably come out of their holes that get inundated with rain-water to seek shelter in gardens and many times in houses. As such they pose a great danger to man. 

 May be therefore, snakes are worshiped on this day. Right from the times when mankind started acquiring some sort of culture, Sun and Snake have been invoked with prayers and ritual worship in most of the countries. In India even before the Vedic times, the tradition of snake-worship was in vogue.

The Legend
In ancient India, there lived a clan by the name of "NAGAS" whose culture was highly developed. The Indus Valley civilisation of 3000 B.C. gives ample proof of the popularity of snake-worship amongst the Nagas, whose culture was fairly wide-spread in India even before the Aryans came. After the Naga culture got incorporated into Hinduism, the Indo-Aryans themselves accepted many of the snake deities of the Nagas in their pantheon and some of them even enjoyed a pride of place in the Puranic Hinduism.
 

The prominent Cobra snakes mentioned in the Puranas are Anant, Vasuki, Shesh, Padma, Kanwal, Karkotak, Kalia, Aswatar, Takshak, Sankhpal, Dhritarashtra and Pingal. Some historians state that these were not snakes but Naga Kings of various regions with immerse power.

The thousand-headed Shesh Nag who symbolises Eternity is the couch of Lord Vishnu. It is on this couch that the Lord reclines between the time of the dissolution of one Universe and creation of another. Hindus believe in the immortality of the snake because of its habit of sloughing its skin. As such Eternity in Hinduism is often represented by a serpent eating its own tail.

In Jainism and Buddhism snake is regarded as sacred having divine qualities. It is believed that a Cobra snake saved the life of Buddha and another protected the Jain Muni Parshwanath. To-day as an evidence of this belief, we find a huge serpent carved above the head of the statue of Muni Parshwanath. In medieval India figures of snakes were carved or painted on the walls of many Hindu temples. In the carves at Ajanta images of the rituals of snake worship are found. Kautilya, in his "Arthashastra" has given detailed description of the cobra snakes.

Fascinating, frightening, sleek and virtually death-less, the cobra snake has always held a peculiar charm of its own since the time when man and snake confronted each other. As the cobra unfolded its qualities, extra-ordinary legends grew around it enveloping it in the garble of divinity. Most of these legends are in relation with Lord Vishnu, Shiv and Subramanyam.

The most popular legend is about Lord Krishna when he was just a young boy. When playing the game of throwing the ball with his cowherd friends, the legend goes to tell how the ball fell into Yamuna River and how Krishna vanquished Kalia Serpent and saved the people from drinking the poisonous water by forcing Kalia to go away.

It is an age-old religious belief that serpents are loved and blessed by Lord Shiv. May be therefore, he always wears them as ornamentation around his neck. Most of the festivals that fall in the month of Shravan are celebrated in honour of Lord Shiv, whose blessings are sought by devotees, and along with the Lord, snakes are also worshiped. Particularly on the Nag-Panchami day live cobras or their pictures are revered and religious rights are performed to seek their good will. To seek immunity from snake bites, they are bathed with milk, haldi-kumkum is sprinkled on their heads and milk and rice are offered as "naivedya". The Brahmin who is called to do the religious ritual is given "dakshina" in silver or gold coins some times, even a cow is given away as gift. 
 

Celebrations

During this time, snakes often seek refuge in houses as their holes in the ground become flooded with rainwater. Due to the danger they pose to humans, snakes are worshiped during this period to protect villagers from harm.

Nag Panchami is celebrated throughout India; however, more festivities are seen in the south than in the north.

The village of Baltis Shirale, which is situated approximately 400 kilometers (approximately 250 miles) from Mumbai, conducts the most outstanding of all the celebrations.

Reportedly, the largest collection of snakes in the world can be found in Baltis Shirale. Visitors from all over the world gather in the village to worship live snakes. Interestingly, despite no venom being removed from the snakes, no one has ever been bitten.

Other popular areas of worship during the Nag Panchami include:

Adiesha Temple in Andhra Pradesh
Nagaraja Temple in Kerala
Nagathamman Temple in Chennai
Hardevja Temple in Jaipur.
In Bengal and parts of Assam and Orissa the blessings of Mansa, the queen of serpents are sought by offering her all the religious adoration. Protection from the harmful influence of snakes is sought through the worship of Mansa who rules supreme over the entire clan of serpents. On this occasion snake-charmers are also requisitioned to invoke the Snake Queen by playing lilting and melodious tunes on their flutes.

In Punjab Nag-Panchami is known by the name of "Guga-Navami". A huge snake is shaped from dough, which is kneaded from the contribution of flour and butter from every household. The dough-snake is then placed on a winnowing basket and taken round the village in a colourful procession in which women and children sing and dance and onlookers shower flowers. When the procession reaches the main square of the village all the religious rites are performed to invoke the blessings of the snake god and then the dough snake is ceremoniously buried.

In Maharashtra, Hindu women take an early bath wear their "nav-vari" - nine yards-sarees, put on ornaments and get ready for the "puja" of Nag-Devata. Snake charmers are seen sitting by the roadsides or moving about from one place to another with their baskets that hold dangerous snakes that are their pets. While playing the lingering melodious notes on their flutes, they beckon devotees with their calls -"Nagoba-la dudh de Mayi" (give milk to the Cobra Oh Mother!) On hearing that call, women come out of their houses and then the snake-charmers take out of the snakes from their baskets. Women sprinkle haldi-kumkum and flowers on the heads of the snakes and offer sweetened milk to the snakes and pray. Cash and old clothes are also given to the snake-charmers. Bowls of milk are also placed at the places which are likely haunts of the snakes.

Elderly women draw pictures of five-headed cobras on wooden planks, recite mantras and pray. The daughters wash the eyes of their fathers with rose flowers dipped in milk and then receive gifts from their fathers. In Hindu homes frying any thing on this day is forbidden by tradition.

The most fantastic celebrations of Nag-Panchami are seen in the village of Baltis Shirale which is 70 Kilometres from Sangli and 400 Kilometres from Mumbai. There people pray to live cobras that they catch on the eve of this pre-harvest festival. About a week before this festival, dig out live snakes from holes and keep those in covered earthen pots and these snakes are fed with rats and milk. Their poison-containing fangs are not removed because the people of this village believe that to hurt the snakes is sacrilegious. Yet it is amazing that these venomous cobras do not bite instead protect their prospective worshipers.

On the day of the actual festival the people accompanied by youngsters, dancing to the tune of musical band carry the pots on their heads in a long procession to the sacred-temple of goddess Amba and after the ritual worship the snakes are taken out from the pots and set free in the temple courtyard. Then every cobra is made to raise its head by swinging a white-painted bowl, filled with pebbles in front. The Pandit sprinkles haldi-kumkum and flowers on their raised heads. After the puja they are offered plenty of milk and honey.

There is one popular legend telling how this festival started. Once Guru Gorakhnath while passing through his village saw a woman praying before a clay-cobra idol. He turned it into a living snake and told her not to be afraid of snakes. Since then this Baltis Shirale and its neighbouring regions worship snakes. Guru Gorakhnath's temple is on a nearby hillock.

Tribals in the interior parts of Maharashtra perform acrobatics and magic shows on the streets. Crowds collect around them to see and touch the snakes which the tribals bring in their baskets to show them off.

There are snake-temples in our country with idols of snake-gods. In these temples cobras are also reared and live snakes are worshipped on Nag-Panchami day.

Important Aspects of Nag Panchami

This so called "snake day" has several important components. In addition to offerings made to the snakes throughout the country during worship and celebration, men and women celebrate the day in these ways:

Cobras are bathed in milk and offered rice as this is thought to offer immunity from their bites.
Women often partake in early baths of milk and wear colourful saris.
Pots of milk and flowers are placed next to holes that are believed to contain snakes as an offering of devotion. If a snake actually drinks the milk it is thought to be the ultimate sign of good luck.
Mansa, the Queen of Snakes, is worshiped in most parts of Bengal during Nag Panchami.
In the Punjabi region, a large dough snake is created and then paraded around the village. The parade is colourful with plenty of singing and dancing; at the end of the parade the snake is buried. Nag Panchami is referred to as "Guga-Navami" in Punjab.
Snake charmers sit alongside the roads of Maharashtra and encourage women to offer milk, flowers and haldi-kumkum (a powdered offering of tumeric and vermillion) to the dangerous snakes the snake charmers carry.
In many villages, snake charmers carry pots containing cobras to a central temple where they are released and then worshiped with offerings of milk and rice.
Mainly in the south of India, people worship figures of snakes made of clay or sandalwood as alternatives to the real-life versions.
No Hindu home may fry anything on the day of Nag Panchami.
Girls who are hoping to marry believe that the cobra offers good luck in their quest for eternal happiness.
