Q: Is the law of attraction based on abstract rules or is it more like about the energy/vibes you send out?
Do NOT expect the Universe, the Divine, A deity of unknown scope - to simply GIVE SOMETHING TO YOU because you ask nice. Get a Clear goal of what you want - then get busy moving towards working for it ie creating an environment that it can come into.

Simply saying "I want money" isn't always it. Have you ever said "I want to win the lottery". ? Then hit a $3 lotto ticket win and WHINED that you didn't WIN THE BIG ONE?

Guess what -- you just said you wanted to win - not how much you wanted that win to be.
So attraction requires movement IMHO - it creates the static in the spiritual soup that draws the good things towards you.

Also you need to practice ACTIVE GRATITUDE - even if you've not gotten it yet - SAY THANK YOU for whatever it is - or for bringing something even better.
