A : Actually, there is none for Highly Evolved Beings. All they do is immediately change their mind if they experience a thought moving through their mind that they don’t wish to manifest.
After a while of doing this, they’ve trained their mind never to consider for more than a nanosecond any thoughts that they do not wish to see begin to take shape in their reality. They just don’t hold onto them. They let them go immediately, and move to a new and more positive thought.
So keep new thoughts moving through your mind if a passing thought is anything but positive. Then, when the thought you are holding is positive, yes, of course feel free to share it with anyone who it might concern, or who might have a reason to be interested.
As for saying one thing and doing what you say, let your word be your bond. And if you don’t think you'll be likely, or able, to do what you're now thinking of saying . . . don’t say it.
If on the other hand you meant it when you said what you would do, but find later that you really can’t because something has happened that has intervened, then go to anyone and everyone to whom you said this thing, and clear it up with them. Tell them the truth. Humbly and gently explain why you won’t be able to do what you said.
