The emotional toll life takes on us, is attributed to our human belief in two powers: Good and evil. Mysticism teaches us to focus on what is; without putting any labels of our judgements. Hence the mind has nothing to criticize if it is evil ( by our concept), or good (also based on our definition of “good “).
Thus we lose the excitement of the “highs” or the good moments, but we are also spared the “lows” of the undesirable situations, events and circumstances!
