Dharma Sunday | The 21 Semdzin Online Event With Lama Karma Justin Wall July 19, 2026 The 21 Semdzin are a series of practices found in the Dzogchen Upadesha tantras, using visualization, sonification, and embodiment to release effort and rest in non-meditation. Originally found in the “Reverberation of Sound” and the “Union of the Sun and Moon” tantras of the Upadesha class of Dzogchen, the 21 Semdzin were codified by Longchenpa in the 14th Century. Each semdzin, “lit. holding the mind” is a practice of using light, sound, and embodiment to release grasping and rest in unfabricated presence. This will be the first of a two-part series.
