Putting your life into the hands of this "power" is really giving up on running the show yourself - so like a prisoner who has "surrendered" you are gonna end up where you end up.
I don't know anyone who has fully given themselves from a spot of total deflation, started doing what those before them had done - just to end up in a worse situation before. This fourth dimension they speak of, the spiritual realm - will provide everything one needs. This has been my experience and I now have faith that things will be ok when I move into the unknown.
I don't know if you'll get financially secure - but I do know that if you can go into this "knowing" that whatever is in store for you is better than what "you" have planned for you - things will be good.
This is almost always seen in retrospect.
all the best on your journey.
