It can be done, just make sure that you do not get confused. Stay focused, visualize and mantralize internally.

I thank the instructor for the help here this transmutation has been very helpful. I notice that after ham sah my mind is concentrated and at least for a short amount of time meditation and self-observation become almost effortless and I have energy. I even feel a slight pleasant heat in my body. I notice that even a couple hours after ham sah I will have brief flashes of heat in my face and body and though my body doesn't get hot to the touch I feel it internally and is random. Is this normal after pranayama?
