I’m not a fan of numerology, nor was Revelation advocating it, nor has the Bible ever endorsed it. Yet I can see numerology and Yoga(depending on what tradition and the aim of the practitioner) as having the same root, one of control of body and/or enviroment, feeding one’s illusions of personal godhood! Now that would seem irrational to me!
Yes, Christians who engage in numerology are participating in an irrational superstition.
