I know that the bellow you tube link has discussed before but I want to discuss the other aspect of issue:

https://m.youtube.com/watch?v=Htu8FchIjg4&t=24s

in the video he says the Etheric realm is very dangerous because the entities that are in the Etheric when see you they want to be in 3d world so they catch you and you bring them to your life when coming back to your body.
But the probelm is that he says different thing in his lesson in PDF as coming bellow:

he says in PDF that the evil entity should ask you and introduce himself to you and then you have to invite him! He says this is a Spiritual Law!

How do you describe this opposition?
Is this Spiritual Law True?if yes ...so how the entities can attack then attach according to above video?
