The focus of Tcherkasski's research consists of a comparative reading of the Stanislavsky System and Yogi Ramacharaka's books, which were a main source for Stanislavsky. Accordingly, Tcherkasski analyzes elements of the System based on Yoga principles. Among them are: Special attention is paid to the idea of the superconscious in Yoga, and in Ramacharaka's and Stanislavsky's theories. Tcherkasski's wide-ranging analysis has resulted in new and intriguing discoveries about the Russian master. Furthermore, he reveals the extent to which Stanislavsky anticipated modern discoveries in neurobiology and cognitive science. In this book Tcherkasski acts as a researcher, historian, theatre director, and experienced acting teacher. He argues that some forty per cent of basic exercises in any Stanislavsky based actor training program of today are rooted in Yoga. Actors, teachers, and students will find it interesting to discover that they are following in the footsteps of Yoga in their everyday Stanislavsky based training and rehearsals.
