Why reversed?

the higher realms and the loving god are out there. I spent alot of time looking externally for things that i could find within, with work. I am very sorry to hear of your loss, and sincerely wish you well in your journey seeking. There is much for us to learn about ourselves in our short lives, much about loving ourselves and one another. My heart wishes you the best:)

So, where, what is the energy they use?

Is electronic equipment ever going to be able to 'tune in' spirits?

I am not sure, and I hope not.

It is my belief that a truly refined being is able to transcend many dimensions. Better to pray and become whole. I don't really believe in death. The more I focus on life and love, the more the concept of death ceases to exist. Not by aversion, but by being more connected with what I understand as God or the higher levels. We have the energy and the equipment already, but I feel the objective is not to merely gain some evp.

No, my objective is to reconnect with my wife so I can get some direction about what she now wants me to do.
I agree, a open channel to spirit 'could be' a bad thing unless it was open to all, imagine the teachings and upliftment the world could have.
Imagine if the terrible grief I and others suffer could be lifted and moved to understanding and just a bit of sadness at the physical loss for now!
