There are some auspicious symbols in Indian culture, that adorn its ancient temples. Temples are meant to a beautiful and spiritual place for the community. Acceptable motifs on the entrance, (not necessarily restricted to it), are creepers, foliage, flowers, Devi such as Ganga and Yamuna (for they bear water and hence cleanse and comfort the dusty and tired visitor), lovers and couples (indicative of fertility) etc. Young, decorated women figures are used to beautify temple premises as in shalbhanjika (i.e., woman holding tree branches), or as a couple (mother, lover). Goddess Lakshmi is an auspicious symbol on the temple door jambh (entrance). Women in Indian culture are considered auspicious for attracting wealth. Goddess Lakshmi, being a beautiful woman, is the goddess of wealth i.e., creates/ increases wealth in a community. This is especially true as men desire fertile women, and when men do, they quite invariably end up creating wealth through their labor in the community, so as to sustain the woman they love and likely their offsprings. In Indian culture, as per the available sculptures, full bodied women, are desired as they are considered beautiful and fertile i.e., they are perfect conduits for attracting wealth in the community in which the women live. Ancient Buddhist temples are also found decorated with beautiful women/couple figures. Ancient Indian society, whether Buddhist or Hindu, was a beautiful amalgamation of spirituality and physical desires.
Indian temples in olden days, were self sustaining due to public donations. High emphasis on temple decoration with both religious and non religious sculptures, is a representation of the psyche of the society of its time. Public donations in a temple were likely to increase if the temple was beautiful and spiritual in the eyes of the public and as per the acceptable social norms should represent society's psyche. In this sense, temples were indeed a reflection of society. The ancient Indian society was deeply spiritual at its core and women (through men), were the threads of societal fabric that made the society prosper. Thus women were held in high esteem. They still are, in philosophical sense at least.
Appearance of warrior female deities, like Durga, Kali etc seems to be a relatively recent phenomenon. Why did women deities need to take such violent forms? Is it in response to the changed attitude of men in society or else to protect the society against external threats or something else?
