One great teaching of the Buddha is that everything in the universe — including gods, men, beasts and all sentient beings — is in a state of constant flux.

One Buddha most popularly recognized in China is Maitreya (彌勒佛), the Buddha of the future.

On his way back to China, Qiu Chu-qi (丘處機) was given all the courtesies and honors befitting the grand patriarch of all Taoists in Genghis Khan’s domains.

Qiu Chu-qi (丘處機) and his eighteen disciples left their home base in Qixia (棲霞) in Shandong in 1219 for Great Snow Mountain (大雪山) in present-day Afghanistan where Genghis Khan was staying with his army on an expedition to the West.

Qiu Chu-qi (丘處機) started practicing Taoist asceticism at the age of 18. He became a disciple of Wang Chong-yang (王重陽), the founder of the “All True” school.

Still another of the Seven “All True” Greats or Quan-zhen qi-zi (全真七子) is Wang Chu-yi (王處一). He is known for divine magic.

Liu Chu-xuan (劉處玄) is another one of the Seven “All True” Greats or Quan-zhen qi-zi (金七子).

After the death of Ma Yu (馬鈺), Tan Chu-duan (譚處瑞), one of the Seven All True Greats or Quan-zhen qi-zi (全真七子) took over as the patriarch of their Taoist school.

Ma Yu (馬鈺) and his wife Sun Bu-you (孫不又) are two of the Seven Greats of the All True sect or Quanchen qi-zi (全真七子).

Another Taoist sect, which is no long as popular as it was, is Quanzhen Dao (全真道). Wang Chong-yang (王重陽) founded the All True sect in Shandong in 1167.
