Rate of Vibration
The process of how fast or slow energy contracts back towards its center point of source field is the Vibration rate.
The process of how fast or slow that same energy expands away from the center point of the source field is the Oscillation rate.
The combination of both the pattern of Vibration (contraction) and Oscillation (expansion) speed is what determines the frequency rate of all energy and things. As our personal, collective and planetary consciousness raises frequency, the matter world, including our physical bodies, also becomes less dense as our frequency increases. 
Law of Vibration
Beyond the material realm and into a realm in which everything is energy is the Law of Vibration. A Natural Universal Law that states that ‘nothing rests; everything moves; every-thing vibrates which forms a rate of Frequency.’ The lower the vibration, the slower the vibration; the higher the vibration the faster the vibration. The difference between the manifestations of the physical, mental, emotional and spiritual result simply from different levels of vibrating energy, or frequencies. So, while the feelings of fear, grief and despair vibrate at a very low frequency, the feelings of love, joy and gratitude vibrate much quicker.
Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium or center point. The oscillations may be periodic such as the motion of a pendulum or random such as the movement of a tire on a gravel road. Vibration is responsible for the motion of a tuning fork, the reed in a woodwind instrument or harmonica, or mobile phones or the cone of a loudspeaker, and necessary for the correct functioning of the various devices. The study of sound and vibration are closely related. Sound, or "pressure waves", are generated by vibrating structures (e.g. vocal cords); these pressure waves can also induce the vibration of structures.
