I don"t really understand this. Are the holes in our energy fields opened up, so letting various spiritual forces and ideas through. But if you do it too much and for too long then the wrong types of spiritual energy gets through? Why are younger people less likely to suffer from this? Is it because the more you do it, the more holes you make?

I think if you abuse any substance for long enough, whether it be weed, alcohol, heroin or crunchy nut cornflakes, it is going to play havoc with your spiritual well being.
