I see. I can accept this.Not having experienced that in its fullest sense I can't answer that with any authority but yes, that makes sense to me. I don't know why it would be any different for us than it would be for him.
I have had a sense, a partial limited glimpse, of what union with God means through spiritual practice. I felt a part of a larger whole but at the same time I remained who I was.
Try to imagine what it might be like to merge your consciousness with that of another being. The result would be one consciousness but there would still be the sense of "I" behind it. So I don't think that "I-ness" ever goes away.
I realize that wanting to preserve my individuality could be a survival instinct, or me being egocentric. However, practicing something that leads to my personality and consciousness being obliterated would be very difficult!
I appreciate your insight.
