Central question: 1.Why did Su Tungpo begin to practice yoga and alchemy?
2.How did yoga and alchemy affect his life?
After delving into Buddhist and Taoist philosophy, to attain the peace of mind and prolong the span of life and immortality, Su Tungpo began to practice yoga and experimented with ”philosopher’s stone.’ But his effort of searching for philosopher’s stone was of no avail, he brought back his common sense and began to wonder whether there were immortals or not.
