This book is based on a talk given by the learned Dzogchen master, Khenchen Tsewang Gyatso Rinpoche, at Namdroling Tibetan Buddhist Center in Bozeman, Montana.
"The subject of this teaching is interdependence. It is of course good
to learn more about interdependent origination because, as we know,
`Buddhism is so vast and so profound that, until one attains
enlightenment, there is no way one can fathom everything.
Interdependent origination, or how all phenomena arise
interdependently, relates to all relative phenomena of the external
world. No matter what explanations we have from modern science,
physics, and technology, everything depends on causes and
conditions, as far as how phenomena arise or come into existence."
