Everything is energy, vibrating at specific frequencies, including each individual human. Humans have the capability, to control the kind of vibration they are emitting, thus drawing in matching or complementary vibrations and changing/creating their experience. Simply, what you put out effects what you get back. This is a constant, though we may not be aware it is occurring. Most people don’t understand this universal law, or may not understand how to exercise the control they have within this law.
