A collection of over 1,000 sacred texts relating to the great Tao
and magical practices thereunto.
This body of works is divided into sections (or Caverns):
The Cave of Truth (titles 1-313) Trances, Spirit Writing and Meditation.
Cave of Mystery (titles 314-614) Powerful Five Talismans, Liturgies, Festival of Cosmic Renewal & other Talismans.
Cave of Spirits (titles 615-975) Revelations given at the end of the Eastern Han Dynasty to Chang Tao-ling, founder of the Heavenly Master Sect.
The fourth (titles 976-1,086), Fifth (titles 1,087-1,152) and sixth (titles 1,153-1,176) Caves are described as supplements to the first three respectively.
The Orthodox One (titles1,177-1,412)
Later Taoist Works (titles 1,413-1,464) completes the edition.
Regretably only a very few of these texts have been translated into English.
