Stimulate means act as stimulus to, stimulus means things that rouses to activity. now rouses means exciting, stirring, to cause or to provoke into action, to ignite, 

Thus, stimulation may be described as how external events (environmental energies outside of the body) provoke a response by causing the human body that has been doing nothing, into the realm of acting or doing something. 

Every act that we physically do or act upon is a stimuli (stimulated event) which derives from a physical presence of energies or a spiritual presence produced by a spiritual event.


People always respond to stimulation by reacting or acting.
