諸真聖胎神用訣/Zhuzhen Shengtai Shen Yong Jue – Various Genuine Holy Embryo Spirit Application Secrets, Number 5

又曰：意中動靜，炁得神通。行道自持，我神光明。斯理之然，然可推而得之也。今世之人，神與炁各行，子與母相離，炁雖呼吸於內，神常運物於外。如此遂使炁無主而神不通，神不通而精自散。又以神為主，以形為宅舍，主人不營於內，日營於外，自然宅舍空虛，而形體衰朽矣。瓦末世道流，每一晝一夜，百刻之中，形炁之得總一萬三千五百息，皆外役於神，無息住於形體之中，而何能冀長生久視之道。

It is also said: “When the Yi contains Movement & Stillness, Qi obtains Spiritual Connection. Walking the Dao of Self Control, my Spirit is bright & clear. This principle is correct, thus it is able to reject or obtain it. For the people of this age, Spirit & Qi move independently, Child & Mother mutually seperate. Although the Qi breathes, it is only Internal, & the Spirit regularly makes use of Things so it is only External. In this way, they unexpectedly cause the Qi to have no master & the Spirit to have no connection, & when the Spirit is unable to connect then the Jing will disperse. Again, use the Spirit as the Master, use the Form as the Residence. If the Master does not exercise control Internally, then the Sun will exercise control Externally. Naturally, if the Residence is empty, then the physique will be decrepit. In an Age where the Dao has degenerated, each day & each night, during innumerable moments, the Qi of the Form must complete a total of 13,500 breaths. In every case, what is External is forced into servitude by the Spirit, not the Breathing which is within the Physique. How can you hope for the Dao of Long Life with Unfailing Eyes?”
