Course in body talk;zam zam for non muslims

Assalaamu Alaikum, I intend doing a course on “Body Talk” and would like to know whether it is permissible or not for me to pursue such a course. My concerns about this course stems from my understanding that “Body Talk” is related to working with energies.

A second question that I have is whether it is permissible for one to offer Zam Zam water to a non muslim.
