We are surrounded by energies of various frequencies. Music is Physics because each note, which is a sound, has a vibrational frequency to match with. Physics is art. Even our thoughts, in spirituality, have frequencies to match with other energies present around us in the form of vibrations, sounds or even the temperature of air.
We have souls and our souls have frequencies. The intensity to which we match these frequencies with the other determines the depth of bond we would share with another person or a goal. In simple terms, believing in yourself and your goal completely while acting on achieving it will lead to its accomplishment.
