An angel is a multidimensional being, created with the purpose of benefitting humanity and the spiritual universe. Each religion has its different view on angels, their hierarchies, and visual appearances, but all agree that angels are powerful beings that serve their god. All angels are given a name and a number that is used to communicate with humans, to send a message of support to those willing to listen. Many angels have been sent to Earth to work directly with humanity, while others have been sent to live as humans to atone for their mistakes, instead of being cast out forever with no chance to learn.
It is not possible for angels to stay inside a human body without a massive reduction in their power and memories. The body would not be able to handle the energy and would simply disintegrate. Many angels can recall their memories somewhat from their time before being sent to Earth, but it is often difficult to recall any because of the limitations of the human brain. Angels often have phantom pains from their astral limbs being missing, and vivid dreams containing past life memories.
It is a common misconception that angels are infalliable and all powerful beings, but the truth of the matter is that angels make many mistakes despite their power, though they are far fewer than the mistakes humans make. They have loyalties and sympathies just as humans do, and are so inclined to act on them. Not all angels are nice and helpful - many were created to wreak havoc on the Earth if their god willed it, and others were created to fight massive wars against spiritual evil. Guardian and healing angels are the type shown to exhibit the most kindness as it is the purpose of their creation. They watch over thousands at a time with grace and ease. These guardians and healing angels are the most likely to be sighted, as they appear to the humans who need them the most. During an appearance, they will take on a temporary human-like form, so as to not frighten the human, who would not be able to comprehend the full form of an angel.
If you have ever felt that you may be an angel, it is entirely possible that you are one currently or have been one before, in a past life or another universe. If you remember your angel name, do NOT use it as your own name or speak of it to anyone. The name of an angel is the name of its true soul. Anyone who knows your true name would be able to forcefully summon you at any time. This name is to only be used by your god and your fellow angels. If you would like to be more connected to your angel identity, try using a name similar to the meaning of your angel number.
