Irina Medvedeva is the most popular of the Russian-language Authors writing about esoteric Eastern teachings. Her books about the ancient Shou-Dao clan are widely read not only in Russia, but also in Western European countries. Interest in the unique form of martial arts Shou-Dao and the universal Taoist philosophy is steadily growing – the book “Training by Water” is now in its fourth edition. A person’s ideas about the world and about himself to a huge extent determine his destiny: whether he will be happy or unhappy, whether he will become a winner or a loser, whether he will be able to manage his own life or will only passively submit to circumstances. The main characters of the book, already well known to regular readers, are faced with the problem of forming a “picture of the world.” Korean Lee, the mentor of Alexander Medvedev, prepares his student for the high mission of the Guardian of Knowledge of the ancient clan. Alexander must learn the main thing: by changing his “picture of the world,” a person changes his own destiny along with it.
