1. 有一天，他们讨论到如何修练才能随时登上天际，乘云遨游于宇宙之间，不受时空之限制。跳出生死轮回，永生于涅盘之境。子桑户、孟子反、子琴张三人相与语曰：「孰能相与于无相与，相为无相为，孰能登天游雾，挠挑无极，相忘以生，无所终穷？
One day, they discussed the issues regarding how to practice so that they could fly up to the heaven, how to roam around the universe, how to free from the limit of time and space and how to transmigrate and finally reach the goal of Nirvana.
