Your happiness does not depend on what others do, but only upon your own vibrational balance. And the happiness of others does not depend on you, but only on their own vibrational balance, for the way anyone feels, in any moment, is only about their own mix of Energies. The way you feel is simply, clearly, and always the indicator of the vibrational balance between your desires and your vibrational offering, which, from your vantage point, you have launched.
There is nothing in all of the Universe more important for anyone to understand than how the vibration they are offering is matching the vibrations of their desires, and the way you feel is your indicator of whether you are allowing your connection to Source or not. Every good feeling; every positive creation; all your abundance, clarity, health, vitality, and Well-Being-and all the things that you consider to be good, are dependent upon the way you are feeling right now and on the relationship that that feeling-vibration has to the vibration of who you really are and what you really desire.
