The life described is less ruled and regulated than Indian society would normally allow. The woman is depicted as roaming about freely and enjoying themselves like Goddess Kali does. Here the seven different types of ‘Veshya’ or ritual prostitutes who are at times employed as participants in sexual rituals have been described. Several rituals like ‘Mahachakra’ and ‘Rajachakra’ have been vividly given in details. The woman is also given the same sexual freedom as given to male devotees.

The text openly says that a woman has no fault in being united with a person other than her husband. It also says that young girls depending on a social context practice sexual union. The text states that a woman who practices Kularcana should choose Lord Shiva as her husband. Young woman are associated with several powerful goddesses. For example; a girl of age of twelve is Bhairavi, age thirteen is Unmukhi, age fourteen is Sodasi, age fifteen is Tara and age sixteen is Kali.
