Post-lineage yoga, also called non-lineage yoga, is a contemporary form of yoga practised outside any major school or guru's lineage. The term was introduced by the ethnographer and scholar-practitioner Theodora Wildcroft. She stated that with the deaths of the pioneering gurus of modern yoga such as B. K. S. Iyengar and Pattabhi Jois, yoga teachers, especially women, have been reclaiming their practice through their yoga communities, resisting commercialization as well as lineage.
Scholars and yoga teachers have commented that post-lineage yoga has evolved in reaction to the image of contemporary yoga as an idealized, fit, young, white female body. They note that the practice is non-denominational, non-hierarchical, and non-authoritarian, matching the contemporary concern for authentic religious experience that works for the individual.
