This is a book for all who still have faith that there is a way to discover and develop themselves without having to go against what their common sense tells them is natural. It is also for people who are mature enough to understand that what is natural for one person can be unnatural for another, and that what is natural for one place and time can be unnatural a thousand years later half-way around the world. The gate to infinity does not lead to a system or institution, but to the depths of spiritual life that can be found in nature.
