Vibrations in our hearts trigger waves of emotion which are felt by all sentient beings wherever they are. We do not usually recognise them as such, though they exist: we are not attuned, if you will. We can learn to attune ourselves to such vibrations, however, if we work with the angelic realms. We need to listen to our hearts and to the hearts of others.
We are all vibrating. We are all resonating with the universe and its core frequencies of love, peace, harmony, truth. If we are open to all possibilities then we can learn to listen and then to hear. You can choose to generate emotions from the vibration of your hearts or we can choose to generate the vibrations in our hearts from the emotions which we sense and feel. The process is the same; reversible. We should consciously choose which way we wish the process to occur. We create our reality when we choose to generate the vibrations within our heart from the emotions we are feeling. The heart, then in turn, sends out its powerful resonances to the universe and calls up on the creative essence to bring forth that which is a vibrational match for that within your heart. Creation in your own experience, whenever and wherever you wish it to be so. To allow the extant vibrations which we feel in our hearts to drive our emotions is to allow the residual vibrations which we sense from others to drive our emotions, which, in turn, feeds back into our own hearts and then out into the universe. Be mindful of that which you feel; that which drives your emotions. Be mindfully creative to conjure the emotions which you wish to feel and thence to fill your hearts with the vibrations which will bring about the change which you wish to see.
