I think everybody has a mission in life.
How can people understand what is their mission in life?

This is a big question and I have asked it myself many times. Personally I still don’t have a precise answer, but I tend to rely on the answer Foal received when he asked (Foal 2, pg. 85 English version):

“It is not for all to truly know what their mission is. ‘Know` though that whatever you do, be it your mission or not, if you do it with Love, it becomes part of it. That in itself, to pour Love out of you in any moment of your life, is already fulfilling the core mission of the mystery of Life. Whoever you are, be it in your Heart.”
