Your life is composed of innumerable variants. Your perspective of reality is heavily influenced by the sum of the impressions coming into your field of awareness. Some of them you tag as positive and some as negative.
Just like the strings of musical instruments, some are slammed harder and out of harmony, others are in perfect pitch.
The harmony of all strings is a hallmark of the skillful person, because it relies in one’s judgment and experience to know how much weight to give for each positive or negative impressions. Go with your life’s flow and tune your harmony.
