I am writing this because several people have asked me this question lately, and so I wanted to address it. This is an opinion piece based on my studies of NDE’s, OBE’s, and STE’s, and so should not be taken as fact but as an educated guess kind of thing.
People want to know how they, too, can have the experiences such as are described in NDE’s/OBE’s/STE’s. Here is my answer:
In many cases OBE’s and STE’s are completely spontaneous. There is no cause for it that can be established. I think it’s possible that these types of experiences are ones that we have planned into our life blueprint – we actually planned to have the experience, in many cases, before we incarnated on Earth. So many people are having these experiences that I also have to think that it’s possible that each one of us might (or at least a lot of us might) have this type of experience sometime in this lifetime.
In the case of NDE’s, there was a life-threatening event. Now, don’t go thinking that you’re going to try to cause this kind of experience by threatening your own life, because it won’t work and in the end, the Universe is going to make sure that you’re kicked in your butt for trying it.
Some people have these types of experiences through meditation. That never worked for me, personally, but that doesn’t mean it won’t for you.
Other people use drugs/plants/mushrooms to get the experience. I don’t recommend that. But some people have had wonderful experiences and have pierced the veil that way.
