Solving problems with both hands
Whatever is unprovable is ridiculed as superstition, New Age nonsense, self-deception, etc. And there are pitfalls: self-deception, gullibility, arrogance and others.
But reaching into the beyond-physical, the mysterious, has advantages as well as dangers. Prayer, ritual, all the ways of looking beyond the senses for a reality that can help us solve our problems, are both natural to humans and skills that need practice. Even talking to plants can be a way of enlisting nature on our side. Why should we try to solve all the problems the world faces with one hand behind our backs? Extend the other, the one that knows mystery is out there.
Speak when no one visible is there. Pray in your own way. Experiment and learn.
