Do not listen to those that want you to focus outward with no self awareness, they blame others and give power to outside influences. They believe they are powerless and they join together in ignorance to spreading ignorance to the world. Ignorance is not bliss, this is what evil is in it's purest form. As the universe is a universe of vibrating atoms that breakdown down into smaller vibrating particles back into physical reality, your positive intentions are a very powerful vibrating particle.
What's happening metaphysically is that you are given off a vibration through your thoughts that is changing you and all beings in the universe are reacting to it in vibrational compatibility. When you start to understand that your intentions literally create your reality, you will truly understand how important you are and the responsibility you have to all that is.
Thank you for your time, and I hope for much success to you in whatever you are doing.
