Spirituality ever remains universal, with its appeal to people of all the religions who can come to and join this Studium Generale or Universal Mystery School for practical training. As opposed to the sealed or codified religions, Spirituality is an open book of God, with the living touch of the Masters who present it from age to age in the spirit of the age. In this scientific age, it is presented as any other science, with mathematical precision and results verifiable on scientific lines.
