Nomenclature, orthography and etymology
'Rangjung Dorje' (Tibetan: རང་འབྱུང་རྡོ་རྗེ, Wylie: rang 'byung rdo rje)
Rangjung Dorje was a noted scholar who composed many significant texts, the most famous of which is the Profound Inner Meaning (Wylie: zab mo nang don, which concern the Vajrayana inner yoga practices.
Schaeffer (1995: p. 16) advises that the text is 'verse' (Sanskrit: karika) in eleven chapters regarding the Anuttarayogatantras:
"Rang byung's most famous, and perhaps most difficult work is yet another verse text, his Zab mo nang don, on the Anuttarayogatantras.
This eleven-chapter work is thirty-two folios in length.
According to a colophon provided by Kong sprul, it was written in the Water Male Dog year, 1322, at Bde chen steng.
The colophons to the present redactions say only that it was written in the Dog Year."
The text and its commentary by Jamgon Kongtrul Lodro Taye has been translated in English by Elizabeth M. Callahan.
It was published in 2013 by Shambhala Publications.
The first chapter covers the 'causes' (Sanskrit: hetu) and 'conditions' (Sanskrit: pratyaya) for Samsara and Nirvana.
The second chapter discusses the esoteric understanding of the development of the body in the womb which has direct relevance to the Generation stage.
The text then discusses Nadis, the fivewinds' Prana/Vayu (Sanskrit) and 'breathwork' (Sanskrit: pranayama) and the 'Four States' which are stages of the Generation Phase.
