From Sahaja Yoga Encyclopedia

All objects and beings are a combination of particles and waves that emit some form of vibration, which may be positive or negative. Positive vibrations sustain the energy of love and harmony. Anything divine in nature permanently emits positive, nourishing vibrations. Both negative and positive vibrations can be transferred from one object or being to another. After Self Realization, the positive vibrations can be felt on the central nervous system as a sensation similar to cool breeze.
