Regarding the post about the Over-simplified body I got a question about the possibility of having the translation of whole source text (Nèiguānjīng – Classic of Inner Contemplation) available.
So to begin a series of contemplation (nèiguān) related articles the Tàishàng Lǎojūn Nèiguānjīng or Classic of Internal Contemplation has been translated to English. Download the English translation here: Neiguanjing.
