I think, am not sure, that I remember the colours of humans. If I get too close to them, when dis-incarnate, I can experience their feelings, more and more intensely.
If I or any other wanted to re-incarnate, then it is easy enough to get sucked in by getting too close to rutting couples. This happens unintentionally to the inexperienced. There is obviously, apparently, dimly remembered, a form of evolution on that plane of existence. We love teasing and helping new ones.
But to return to the thought that drove me to write this: It is almost impossible to reach incarnated beings. They must want the contact and for them to even know I was there would be almost impossible. That is why contemplatives, monks and nuns can be very special, no matter what their religion! It is very frustrating to be aware of human suffering through ignorance based upon incorporation and therefore, original sin, as we cannot help them, except to die well.
