I wonder if she then proceeded to give you a definite list of how exactly she knows all of this and how it is proposed to be true, just kidding. I suppose you don't need evidence if the advice seems good enough. You can tell that by the seeing that doing yoga&meditation daily will definitely create better states of mind that just senselessly masturbating all day.
Still, I kind of had a vision of you trying to be good but still hiding behind masks and being unwilling to change yourself. Is that true? I wonder what your manipulative ways are? I find most of this is just applying to myself to.
To be honest I find advice like this utterly useless, that is when hearing it from another human. 'Easier said than done' always applies. What the person lacks here is an understanding of how to achieve that or even an ability to constantly make it a focus throughout their day, it's to easy to forget and just keep acting out of habit. You can lead a horse to water but you can't make it drink, I wonder if that female entity knows about that sort of thing or whether she will do the same thing if you go straight back in there with a stern attitude for understanding?
