One does get the sense, after sitting and thinking of someone you care about deeply, and wishing the best for that person, and sending your love out to that person, that there is a transmission of some kind.
I assume this is what Christians mean by “I pray for you”, and I get it. You want the best for someone, you wish them the best with your entire being, and you get the sense that something was sent their way. Or you’ve shifted the cosmic order ever so slightly in their favor.
To describe what I think it is is pointless, because the only thing I’m certain of is that I don’t know. Who cares? It’s an experience you can have, and one I wish to have more.
