Angels have several purposes; & some of them require certain measures... Walkers (Angel otherkin) are angels who chose to incarnate for some purpose that was better fulfilled in human form... Some walkers choose to incarnate to guide & protect certain people... Some are sent on important charges (purposes)... Some choose or are sent to incarnate to mend an inbalance within themselves... (corruption, negativity) some use the term "fallen" but I think it is rather harsh as it is a process; not an act.
We generally "awaken" by memories of ourselves or simply other places & times... When we awaken we are usually sparked with an interest in angels, theology, mythology & history... These when they are studied; generally bring more memories. We also gain direct contact & communication with guides who are not walking; & gain a family tie or working relationship with them...
With our memories generally comes a longing for being "home" or back near the source, sometimes even back to the times we remember as more free.
Our relationships are generally one sided because we are always meeting people who need our help... We find ourselves listening to life stories from complete strangers who say something like "I can't believe I'm telling you all this; it's not me." & the relationships we have with people (besides other guides) is usually short-lived... diminishing when we have done all we can in guiding, healing, protecting or supporting that person... We also have many physical, phsyicich, mental & empathetic strengths & powers... Our weaknesses tend to come from inbalances; we generally only become ill with negativity.
