I just know that if I want to do something physical for someone else, I have to do it for me. Not to receive something back, not to accomplish any physical condition. But I do it because I feel love, appreciation, joy, freedom, happiness, passion, excitement, and any emotion that feels wonderful to do it.
Conditions may help you in your way to feeling wonderful, but you don’t have to become dependent on any condition. You may like to hear “thank you” when you are doing something for someone. But this doesn’t have to be your purpose, you don’t have to do it for the ‘thank you’, just do it because it makes you feel wonderful emotions to do it.
I think this is the meaning of SELFishness. To do things that make you feel wonderful emotions to do it.
Because you know that if you feel wonderful emotions, you are in sync with your Inner Being, you are in sync with your vibrational reality(VORTEX), you are acting under the influence of Source, you are more likely to receive the inspirations that will lead you to the accomplishment of your desires, AND you are sending good vibrations to the Universe and Law of attraction will match those vibrations with great things.
