Anuyoga-yana is associated with the feminine principle and is for those whose principal obstacle is passion. In anuyoga the emphasis shifts away from external visualization toward the completion stage, in which one meditates on the inner or subtle body with its primary energy centres ("chakras"), and its "prana" (winds or subtle energies), "nadis" (the inner pathways along which one's energy travels), and "bindu" (the consciousness). In anuyoga, all appearances are seen as the three great mandalas, and reality is understood as the deities and their pure lands.
