As the day and age is currently you cannot truly expect there to be scientific evidence to support many claims of spirituality. The jews block any and all spiritual research and fill it with their bullshit. Let's talk about masturbation and why it can be healthy for you. When you preform sex magik you put all of your visualization and intent into the person at the point of orgasm. The reason for this is that when you reach a climax all of your bodies chakras open near simultaneity and you are put into a very deep trance for a moment. Lack of ejaculation is not good for you if you aren't spending 10 hours a day making sure EVERY chakra has energy flow into it. Upon climax your chakras are opened(not completely obviously, but they are activated) and this helps with the health of your soul and balance of your health. Over masturbation can be harmful. I personally recommend once every one-two days putting your climax to a specific purpose. If you do not have a purpose in mind at the point of climax give your sexual energy to Satan by saying something along the lines of "I give all my sexual energy to Satan for whatever purpose he defines". That way your energy goes to Satan and not getting wasted.
