The inspiration is the life force of the entire creation. All the major and minor energies and forces are represented by various goddesses. Navratra deity Durga and all her dimensions are believed to be the manifestations of the same basic inspiration Mahamaya.
Thus, a virgin girl is the symbol of the pure basic creative force according to this philosophy.
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. If a person is desirous of attaining Tantrik-power, Sammohan (hypnotizing), Uchchatan (causing hurdle in the path of other success), then he should worship a shudra-girl-child.
