This Authority requires the Solar Plexus, Sacral, and Spleen to be undefined and the Heart defined, connected to the Throat in Single Definition. Indeed, that would make this is a Manifestor exclusive Authority.
Nobody said it better for Ego Manifestors than Alister Crowley in the Book of the Law: "Do what thou wilt shall be the whole of the Law. Every man and every woman is a star. Love is the law, love under will. For pure will, unassuaged of purpose, delivered from the lust of result, is every way perfect." Or you could just say: "Do what you want!"
The heart is very straightforward, you want what you want and that's just the way it is. In essence, you are designed to follow your powerful will and your heart's greatest desires. The biggest problem with this is other people, as with many of the Manifestor's endeavours. The best approach is to always follow the Manifestor's Strategy of informing before initiating anything that would likely affect others. This way people will be less likely to get in the way of you and what you want.
The other thing about the Heart centre is that it wants to be the first, it wants to be the best, it wants to be in control. It makes promises and sees them through, so be careful that you aren't getting swept away by other people's will and desire. You can also end up taking on so many commitments and making so many promises it becomes humanly impossible to see all of them through. Such is the human ego. We will do so much to feel worthy to ourselves and others.
Let's go back to The Book of the Law for a minute: "Every man and every woman is a star." There you have it, what more would you like to be? We are all stars and we are all made of stardust. No man or woman is more or less than a perfect star, born to shine light through their unique lens. However, its deeper than that, its also touching on how any extension of consciousness includes all other consciousness. The Monad is One and All and so It is. Every Experience is an aggregate of the original source in its perfection.
"Do what thou wilt shall be the whole of the Law. Love is the law, love under will." Here it's saying that there is no Law other than do what thou wilt. The Law is love and that any individual should do what they love most under their will. "For pure will, unassuaged of purpose, delivered from the lust of result, is every way perfect."
If you become too attached to results you're in trouble, because what happens when you don't see those results? It adds resistance to what you are trying to manifest. In reality, if you will it, then so be it. Lusting after results means that you are uncertain of the power of your will to manifest, so you have to rely on results to prove that you can manifest what you want. Human beings are creative and imaginative infinite spiritual entities. The only limitation on your life is your own mind.
