How can an angel be bullied? Can angels feel anything akin to physical pain, or is angelic pain emotional only? Can only their feelings and self-esteem be affected?

Angels are bullied all the time by agents of the darkness and go toe-to-toe with one another in direct contests for predominance in many situations when people are struggling and suffering and being preyed upon by dark spirits, whether human, extraterrestrial, or the fallen angelic, spirit meddler, demonic beings. The difficulty the angels have is they must show restraint because they can only exert a force proportional to the level of desire and specific requests coming from the physical side. You are assigned angelic guardians, but if you do not perceive this or believe in it, and especially if you do not believe in your own self-worth, your guardians may be helpless to rescue you from dire circumstances, and so this is why bullying of angels comes about, it is not their weakness but yours. This will be felt emotionally but there are perceptions akin to physical ones felt by higher dimensional beings, and this is beyond your understanding but reflects the fact that you will not lose anything in moving up in status and stature going to higher dimensions, it will only get better and not be more limited in the richness and variety of experiences you will enjoy.
