You know in the writings of Swami Vivekananda and Yogi Ramacharaka and several others I've read they describe various mental practices, breathing practices, etc. that just have to be done and then you reach conclusions after. These are "religions" where belief is not first but is the effect. The religions that are dying are the ones that start with faith but the religions built on introspection, personal experience, etc. are going to continue. When you examine your own mind through meditation and examine reality through careful reasoning and so on you can reach some very interesting results about the nature of the self, reality, the absolute, etc.

Christcuckery is dying out because it's completely divorced now from experience and practice. It's just dead words and people muttering about what they don't know and demanding others make the same mutterings.
