The azure sky with fleecy white clouds and the nip in the air marks the advent of autumn – the season for Bengal’s most popular festival, Durga Puja or the worship of Goddess Durga.

Durga Puja is celebrated with customary pomp and fanfare twice a year – once in the month of March or April (basant) and again in the month of September or October (ashwin), during the moonlit fortnight. On both the occasions, the puja is a nine-day affair with the last day coinciding with Ram Navmi and Dussehra respectively.

Navratri is devoted to Amba mataji. In some homes, images of mataji are worshiped in accordance with accepted practice. This is also true of the temples, which usually have a constant stream of visitors from morning to night. The most common form of public celebration is the performance of garba and dandia-ras/ras-garba (a form of garba with sticks), Gujarat's popular folk-dance, late throughout the nights of these nine days in public squares, open grounds and streets.

Durga Puja commences on the day after mahalaya, usually on the last day of the waning or new moon, sometime in September or October. On mahalaya, melodious strains of agomoni (welcoming) and chandi path (readings from chandi, a religious Hindu text) exude from radios and television sets. The countdown to the final days of the Puja itself begins from the day of mahalaya. This is around the period when people indulge in last minute shopping sprees. So if you don’t like crowds, this is not the time to visit markets, especially in Bengal.

The Durga Puja is celebrated in various parts of India in different styles. But the one basic aim of this celebration is to propitiate Shakti, the Goddess in Her aspect as Power, to bestow upon man all wealth, auspiciousness, prosperity, knowledge (both sacred and secular), and all other potent powers. Whatever be the particular or special request that everyone may put before the Goddess, whatever boon may be asked of Her, the one thing behind all these is propitiation, worship and linking oneself with Her. There is no other aim. This is being effected consciously or unconsciously. Everyone is blessed with Her loving mercy and is protected by Her.

Durga Puja or Navaratri commences on the first and ends on the tenth day of the bright half of Aswayuja (September-October). It is held in commemoration of the victory of Durga over Mahishasura, the buffalo-headed demon. In Bengal Her image is worshipped for nine days and then cast into water. The tenth day is called Vijaya Dasami or Dussera (the "tenth day"). Processions with Her image are taken out along the streets of villages and cities.

The mother of Durga (that is, the wife of the King of the Himalayas) longed to see her daughter. Durga was permitted by Lord Shiva to visit her beloved mother only for nine days in the year. The festival of Durga Puja marks this brief visit and ends with the Vijaya Dasami day, when Goddess Durga leaves for Her return to Mount Kailas. This is the view of some devotees.

Durga Puja is the greatest Hindu festival in which God is adored as Mother. Hinduism is the only religion in the world which has emphasised to such an extent the motherhood of God. One's relationship with one's mother is the dearest and the sweetest of all human relations. Hence, it is proper to look upon God as mother.

Durga represents the Divine Mother. She is the energy aspect of the Lord. Without Durga, Shiva has no expression and without Shiva, Durga has no existence. Shiva is the soul of Durga; Durga is identical with Shiva. Lord Shiva is only the silent witness. He is motionless, absolutely changeless. He is not affected by the cosmic play. It is Durga who does everything.

Shakti is the omnipotent power of the Lord, or the Cosmic Energy. The Divine Mother is represented as having ten different weapons in Her hands. She sits on a lion. She keeps up the play of the Lord through the three attributes of Nature, namely, Sattwa, Rajas and Tamas. Knowledge, peace, lust, anger, greed, egoism and pride, are all Her forms.

You will find in the Devi Sukta of the Rig Veda Samhita that Vak, symbolising speech, the daughter of the sage Anbhirna, realised her identity with the Divine Mother, the Power of the Supreme Lord, which manifests throughout the universe among the gods, among men and beasts and among the creatures of the deep ocean.
