The relation of Purusa to Prakrti—the unfolding force of nature—becomes here a relation of male to female. This is expressed in the Siva temple in the core image of the sivalinga, an expression of male (linga) and female (yoni) union. The basic cosmogonic motif of an unfolding or flowering cosmos is expressed here specifically in the relation of male to female, as well as in terms of consciousness and intentionality (in the concept of lila as the divine play of male and female). As such, the core saivite image of cosmogony as the flowering of consciousness and sexual union rather than the sacrificial act. This theme resonates with other Hindu doctrines, such as Tantra and Sakta.
