Fortune must be sought from within oneself; destiny cannot be entrusted to others. The interplay of yin and yang is the Way, where the alternation of cold and heat, the cycle of the seasons, and the constant change between ascent and descent embody the unchanging law of the universe. Prosperity and adversity follow the course of time. By aligning with the natural order, one receives divine favor, and all will be auspicious. The past cannot be reclaimed, but the future is still within reach. The Way of Change is explained, moving from the superficial to the profound, starting from the ordinary and reaching the divine. This is the essence of the account holder’s philosophy
