1) Hindu yoga — Swami Satyananda (also, all other teachers that stem from his teacher, Swami Sivananda); this entails the foundations of advanced yogic sādhana, such as prāṇāyāma and midline energy work. Āsanas find double duty as a vehicle for physical cultivation and energy cultivation (by incorporating expanding and sinking qigong into the practice).
2) Tibetan Buddhism — Dzogchen: Bön tradition (mainly Tenzin Rinpoche) and Nyingmapa tradition of Dudjom Lingpa (mainly Lama Alan Wallace); Vajrayana: Kagyu, Bön and all other Tibetan Buddhist traditions for generation and completion stage practices, especially phowa, tummo and 8 yogas of Naropa (Tulku Lobsang Rinpoche, Tenzin Rinpoche, Lama Zopa, Patrul Rinpoche and many others)
3) Daoist yoga — Chinese medicine (acupuncture and medical qigong) provide the foundation (for instance, Jerry Alan Johnson for medical qigong); Neidan (qigong for the central channel): Parting Clouds Daoist Education, a sect of Quanzhen Longmen, this Daoist community provides formal training toward ordination which includes neidan as part of the curriculum; and the Dragon Gate lineage as taught by Wang Liping (see Nathan Brine's books: The Taoist Alchemy of Wang Liping, volumes 1 and 2; Nathan is authorized to teach neidan by Master Wang Liping).
