When I come into contact with those who see things from a merely materialistic point of view, i.e. the mechanistic Universe, sometimes I can become discouraged, frustrated, fearful, angry, and thus perpetuate those states by letting those energies take over, and sending them onward to others.
The means of overcoming that state are available to all of us. Another quotation from the Kybalion comes to mind:
"Nothing escapes the principle of Cause and Effect, but there are many planes of Causation, and one may use the laws of the higher to overcome the laws of the lower."
