In this post, I wrote, "Most of us live abroad our entire lives without ever experiencing the peace, serenity and beauty of being in our proper place. If I could gift something to humanity, that gift would be feeling this."
Someone asked me for "peace" when s/he knew a rough day lay ahead. I using a white pentagram, I created a door to what I think may be this person's equivalent of an astral temple of Malkuth. I emoted peace there. It has been reported that this person has felt extreme peace for many days now.
This has to be the coolest thing I've managed to do for someone with magic. Giving the gift of peace, no matter how short lived, is simply awesome.
