The "Koan Sutra" was a marvelous ancient book of Taoism. The Taoist Founder Master Luc Dongbin once said, "The most serious mistake is only cultivating physical life without altering natural instincts; but if one only practices characters without training immortality, hellish souls caught in vast disasters will be hard to become holy."
This was a formula of cultivating lives.
Of course, it was not the usual books of Taoism that were circulating in the market but instead, came from the hidden chapters of the Koan Sutra
Tai Yinzi afterward described some of its contents. This was probably what he understood from his master’s words.
A lifetime is a complete circle. Whether experiencing awful sadness and great happiness, or feeling delicate emotions, the goal in life is sincerity. Completing cultivation is like waking up from a dream - reflecting on the past, and then being reborn into the next stage of the circle.
