You can read yoga, especially Kundalini yoga books that specify in great detail what happens if you acitvate the chakras with kundalini energy.

Form the perspective of the science of the supernatural that I am promoting, what the yoga books say translates into one obtaining various degrees of consciousness in the supernatural world.

However, I have no personal experience of this. I just hope it is true and that maybe after I die I will automatically have consciousness in that world. But most likely if I do, it will be a gift from god. It would be hell to live in a supernatural world that you are not conscious of.

Come to think of it, that`s where we are now. But at least we are conscious of the physical world. That may be lost in the afterlife.
