Any negativity harboured within oneself towards the WAS will come back to us, whether it is conscious or not.
Actually, let me be a little more clear on that. It is understood that what is in our unconscious mind... what our unconscious mind focuses on, is what goes out to the universe and we get back.
I have heard it this way, spoken about some of the best leaders, movers, and shakers...
They will focus on something, very clearly (visualization)... and then... the purposely and specifically stop consciously thinking about it. Eventually, what they were thinking about, or the problem they were trying to solve, arrives to them... as if by "magic"...
