Use your life as a testing ground, or laboratory for the principles you are learning. That's what I do.
“The world mirrors our own emotional state and vibrational frequency,”
Let's test this principle by trying the following:
The next time you are in a tense, stressful situation with someone or thing, (your pet/child/spouse/boss/etc), contain your outer reaction and look inside for an honest evaluation of your own thoughts/feelings. Listen to your judgments about the person /thing/situation and look for where you are holding the same or similar judgments towards yourself.
Now decide not to react in any sort of negative way to the situation at hand. Choose instead to look for the gift in the situation or something about it you can appreciate. Insist on elevating your own frequency by thinking positive thoughts and notice how the external situation shifts to reflect your internal adjustment.
Turn your life into an experiment for Truth. It will accelerate your movement towards peace.
