would you be able to grow wings or claws or horns in a type of energy form, like the astral body but have it while you are in your physical body? this has been on my mind ever since i heard about modifying the body by means of magic.
Are you asking if you can use will power to extend and shape your own natural energy into a specefic form. If so, then yes. I have done it. Although it takes a lot of practice and experience in energy work.
