"Within yourself lies the cause of whatever enters into your life. To come into the full realization of your own awakened interior powers, is to be able to condition your life in exact accord with what you would have it." These words set the keynote of Trine's message in In Tune with the Infinite, in which he sets forth with simplicity and clearness the application to practical life those spiritual laws that make for the "fullness of peace, power, and plenty."
