What if any value does NLP, hypnotism, and non verbal communication play in spirituality?

Answer 1

These communication skills and concentration aids are helpful in dealing with other people, and they've been used by charlatan evangelists to con their flocks, but in general, they are techniques that are void of any ethical or spiritual dimension.

When used by a skilled and ethically bound therapist, however, they can be useful for helping people make desired changes in their lives.

Answer 2

everything helps
