Basing his work mainly on the teachings of Yongdzin Lopön Tenzin Namdak Rinpoche and Khenpo Tenpa Yungdrung Rinpoche, Dmitry Ermakov - a long-time student of Bön - explores how the Bönpos have for centuries harmonized their environment with techniques based on a profound understanding of the interaction between the mind and the external elemental forces. These teachings are mainly contained in the cannons on Causal Bön, the first four of the Nine Ways, and this new book contains many extracts from seminars and teachings given by Yongdzin Rinpoche on this subject, and on the archaic culture behind it. Concepts underlying such important offering rituals as Sangchöd, Chutor, Sur, Chöd and Tsok/Ganapuja - fundamental to both Yungdrung Bön and Tibetan Buddhism alike - are looked at in detail, and practices such as Lungta prayer-flags and purification rituals are also examined forming a sort of 'companion guide' to the practices themselves. The Guardians, yidams, gods and spirits of Yungdrung Bön are introduced and discussed, Bönpo mythology and cosmology are examined and compared with modern science, there are detailed descriptions of the Six Realms of Rebirth, of the Bönpo understanding of Tantra and Dzogchen, and the revolutionary role of the Central Asian Buddha Tonpa Shenrab Miwo is highlighted. In short, for a practitioner these explanations, which are clearly presented with many illustrations, can provide a key to a deeper understanding of practices which are performed throughout the international Bön community on a daily basis.
