When these things occur, Karma is trying to teach us lessons that we need to learn - RIGHT NOW! Perhaps we ignored gentler warnings and the only way to get through is to throw horrendous catastrophes at us. I don't know about you, but I've certainly been stuck in my groove with tunnel vision enough so that I wasn't looking at the BIG picture. When these kind of changes happen we need to really try to get past the pain and dig deeply beneath the surface of events in order to figure out what is really happening and how we can build our tower back up on a more stable base. There is ALWAYS a message - we just need to figure out how to connect and move forward.
I wish you all many blessings and hope that your "Titanic" experiences teach you the valuable lessons you need to learn!
