Yogi Ramacharaka 
Mystic Christianity [EPUB ebook] 
or The Inner Teachings of the Master

In Mystic Christianity-Religion, Philosophy and Science are known to be one and the same thing. There is no conflict between Science and Religion, Philosophy and Religion, or Philosophy and Science. They are all but names for the One Truth. There be but one Truth-there cannot be more than one. And so call it by the name of Religion… the name of Science… the name of Philosophy… it matters not-for the same thing is meant. There is naught but Truth. Nothing else really exists. All that is not Truth is Illusion-Maya-Nothing. And Mystic Christianity is based upon the Rock of Truth-fearing not the winds nor the storms that try out the stability of all structures of thought. Like its founder, it has always existed… always will exist… from the Beginningless Beginning… to the Endless Ending.
