Kanjak pūjā (कन्या पूजा), is a Hindu holy day celebrated on the eighth and ninth day of Navaratri festival. Nine young girls representing the nine forms of Goddess Durga (Navadurga) are worshiped. Thus, girl-child is the symbol of the pure basic creative force according to this philosophy.
It is a custom to wash the feet of these nine young girls as a mark of respect for the Goddess and then offer new clothes as gifts by the devotee. Kanya puja as a part of Devi worship is to recognise the feminine power vested in the girl child and to give them as much importance in the social fabric as the so-called heir apparents (boys) who are otherwise known to be pampered in an average household.
If the worshiper is desirous of acquiring knowledge then he should worship a Brahmin girl child. If he is desirous of acquiring power, then he should worship a Kshatriya-girl child. Similarly if he is desirous of acquiring wealth and prosperity, then a girl child belonging to a Vaishya family should be worshipped by him. There is also a ritual purification and chanting of mantras. She is made to sit on a special pedestal. She is worshiped by offering ‘akshat‘ (rice grains) and by burning incense sticks. She is worshipped because, according to the philosophy of ‘Striyah Samastastava Devi Bhedah’, women symbolize Mahamaya (The goddess Durga). Even among these a girl child is considered to be the purest, because of her innocence.
Hinduism believes in the universal creative forces to be feminine gender. The very original force is Mahamaya whose inspiration created the gods and the rest of the cosmos. The inspiration is the life force of the entire creation. All the major and minor energies and forces are represented by various goddesses. Navaratra deity Durga and all her dimensions are believed to be the manifestations of the same basic inspiration Mahamaya.
Religiously speaking, Devi is essentially a worship of the great feminine. In a kanya the great feminine potential is at its peak. having developed into a girl of a certain age and before attaining puberty, a female child is considered the most auspicious, most jagrat, and the most clear minded and clear souled individual. While invoking the parashakti in such a form the purity of mind body and spirits is required and is fulfilled by a girl child of the said age of 8+ before reaching puberty. Such a female child is indeed Devi, who in her later life takes the roles of Parvati as a wife and mother, Lakshmi as a housewife, Saraswati as the first guru of her children, Durga as the destroyer of all obstacles for her family, Annapurna as the food provider through her cooking, Kali as the punisher to bring the members of the family on the right track, etc.
