Let's say you really want to manifest a great deal of money, but don't consider the highest good, you run the risk of getting that money, but creating " lack" someplace else.
So how do you know that you're are in alignment with the highest and greatest good?
Ask your heart what it thinks is for your highest and greatest good. Are you certain you know what you want? Then ask your heart if it's for the greater good?
Don't focus on the results; you could be creating a state of want and you don't "want" to do that Remember to stay focused on the positive energy, light and love that comes with what you're trying to manifest.
Blessings to you! As always; Peace, Light and Love to all!
