The eleventh century Amṛtasiddhi teaches, for the first time, bodily practices that become central to haṭha yoga. The startling teachings are explained systematically, in terms of the nature of the body, the practices, and the results of the practice in this tantric Buddhist source text. In this course we will read the Sanskrit and discuss in English the section on ‘the body’ as set out in the first ten chapters of the Amṛtasiddhi. The course comprises four online sessions and one in-person workshop in London. Online 26 Sept 3, 10, 17 Oct 2023 18.30 – 20.00 (Zoom). In-person 21 October 2023 11.00 – 14.00 (The Shala, Drummond Street, Euston, London). The recommended course fee for all sessions is £100.00; in-person (alone) £45.00; or choose your own donation amount. Selecting this ticket type allows you to select the donation you are able to afford. The cost of the course is calculated on accessibility, affordability and a living wage. Enrolments are capped to ensure everyone can talk and be heard. Sessions are open to all - practitioners, scholars, the curious. No previous knowledge is required and the sessions will start by setting out key concepts and contexts before diving in deep. Online sessions are held on zoom. Sessions will be recorded and available to participants to re-watch within one week. Please do not circulate these recordings or make your own recordings. The in-person workshop will not be recorded. The in-person workshop will explore the physical practices in an accessible manner as well as discussing the ideas behind the practices.
