I'm a Pranic Healing instructor in Pennsylvania. Our classes are 2 days - full day Saturday, full day Sunday. All in person. By the end of the weekend, everyone understands how energy (Prana) works, and they're using it to heal simple physical ailments.You do need the IRL work! Students practice with each other, continue learning on breaks - sometimes we even have animals in classes! At my class last weekend, one student brought a dog. In addition to practicing on each other and distant healing, everyone practiced some of the techniques on the dog.
