All religions have originated from One and the same Source. As we go further away from the highest spiritual realms, the various religions begin to differentiate one from another.
But these differences are only seen on the levels of manifestation, on the formative aspect of things. Their essence is the same.
That's why the enlightened ones, mystics, saints, and holy people of all religions easily find common language, and understand each other so nicely. In contrast, people blinded by the form, see different rites, different clothes, different prayers, different visual aspects, etc., and fail to see the one and the same essence of true cosmic love and unity.
So, I believe, our aim is to find these common aspects of all religions, not in the manifested visible world, but in the regions of our hearts and souls and our inner life. Then we will see the great unity that exists in spite of all the seemingly apparent differences.
