Reinhard Gammenthaler (born May 9, 1953) is an initiate of the ancient Ashtanga-Yoga and renowned Yoga teacher from Switzerland. He is the last disciple of Yogi Swami Dhirendra Brahmachari, the successor of the great seer and holy Yogi Shri Maharshi Kartikeya. His book, Kundalini-Yoga-Parampara: The Living Tradition of Kundalini-Yoga, a comprehensive work on the practice and philosophy of Hatha-Yoga, has been published so far in German, English, Russian and Czech. It continues the two books by Dhirendra Brahmachari, Yogic Sukshma Vyayama and Yogasana Vijnana and completes them with a third part concerning the techniques of Mudra and Pranayama; it also includes detailed information on essential aspects of the original Yoga, such as diet, lifestyle, Cakras, Nadis, Marmas et cetera. Deeply impressed by the ancient Indian epic Bhagavad Gita and ancient scriptures such as the Hatha-Yoga Pradipika, the Shiva-Samhita, the Gheranda-Samhita and the Yoga-Sutras of Pantajali, Reinhard has been practicing Yoga according to the teachings of his Guru Dhirendra Brahmachari since 1979. After years of preparation in Switzerland and West Africa, Reinhard met his teacher in person for the first time in India in 1989. Dhirendra Brahmachari accepted him as his final disciple and sent him to Mantalai, a small mountain village in a remote valley in the Indian part of Kashmir. There, in complete isolation at the Aparna-Ashram, he underwent rigorous Sadhana to learn the many techniques and aspects of Pranayama, Mudra and Svara as set forth in the ancient scriptures of the Yoga-Shastra. In 1993, he received Diksha (initiation) from his Guru into the Parampara (tradition as it emerges from the teachings of great Yogis such as Swatmarama, Goraksha and Matsyendra) of the original Hatha- or Kundalini-Yoga. The Parampara is based on Ashtanga-Yoga (eightfold Yoga path) and consists of Hatha-Yoga (Yoga of power) and Raja-Yoga (royal path). Hatha is the foundation of sometimes very demanding physical exercises that ultimately lead to Raja, the royal path of meditation, supernatural realization and liberation. Ashtanga-Yoga includes all aspects of Yoga, such as Bhakti-Yoga (path of devotion), Karma-Yoga (path of selfless deed) and Jnana-Yoga (Yoga of knowledge and wisdom), the synthesis of which enables the Sadhaka (seeker of spiritual realization) to master the perilous and arduous climb to the heights of self-perfection. In 2002 Reinhard began teaching Yoga and founded a school for traditional Hatha- or Kundalini-Yoga in his hometown of Bern. Since 2005, he has regularly given international Yoga workshops. In early 2020, he moved to Oberburg in Emmental, where he will inshallah teach at Yogahaus Oberburg from summer 2022.
Reinhard appears in the documentary film Yoga – Der Ruf der Stille (2009) by Kurt Widmer for NZZ Format, where he talks about his view of Yoga and demonstrates advanced yogic purification techniques and Asanas.
