Sutra1.2. Chitta-Vritti-Nirodha and Shamanic Experience

In this blog, as well as in other works of mine, I have more than once mentioned shamanic roots of yoga much as of other psychopractices. However there comes a question: are the key goals and practices of yoga as laid down by Patanjali correlated with analogous goals and practices of shamanism? It may be difficult to see the commonality at first (and unsophisticated) glance; but in terms of a more detailed analysis based upon an attempt to comprehend the underlying content of the psychotechnical experience described by means of available metaphors rather than the externals that each system is known by, the continuity of shamanism and yoga in this aspect will become obvious.
