This book offers a social-scientific interpretation of the Hindu and Buddhist traditions of Tantra dating back 15 centuries. Using personal praxis to inform his research, the author examines three core themes within Tantra - a 'holonic'/mandalic individuality that conduces to mystical experience; a positive valorisation of pleasure and play; and cultural attitudes of gender-mutuality and complementarity, as neatly encapsulated in the icon of Shiva as Ardhanariswara. This analysis, as captured by the Tantric mandalas of deities in intimate union, leads to his compelling metathesis that Tantra serves as a permanent counterculture within the Indic civilization.
