Hm, some say, true spirituality is not about seeking miracles. You may like them as "proof" that the system is legit, but they are also "simple indulgence", and can lead you astray
Also, beware of confirmation bias. There are some amazing examples of this in martial arts, people who think they can be invincible by "settling their Qi" or something like that
Beware of spiritual advice from non-spiritual people...
