This article considers issues of authorship and textual development over the generations, focusing on the contributions of the erudite scholar/lama Dudjom Jigdral Yeshe Dorje, to the revelations of Bhutan’s national saint, Pema Lingpa, on the tantric deity Vajrak?laya. Dudjom Rinpoche compiled a number of ritual practice texts for this revelation cycle, also writing commentarial instructions on them. Here, two of his compilations are examined in detail, considering how they relate to the original revelation, what they add, and what they neglect, reflecting on what they might tell us about Tibetan approaches to continuing textual production in revelatory traditions. Much of Dudjom Rinpoche’s ‘Ultra Secret Razor Lifeforce’ Framework text for the Major Practice session reproduces virtually unchanged his earlier Framework text for the Dudjom tradition ‘Meteoric Iron Razor’, which itself draws on Guru Chöwang’s ‘Ultra Secret Razor’, as presented by Terdak Lingpa, the founder of Mindroling Monastery in central Tibet. On the other hand, Dudjom Rinpoche’s main Ritual Manual for Pema Lingpa’s cycle is more clearly rooted in the Pema Lingpa cycle, but there has been considerable re-working of the phrasing and even of some key visualisations. Some of the significant modifications were already present in an earlier Ritual Manual of the third Sungtrul or Pema Lingpa reincarnation, Tsultrim Dorje, and Dudjom Rinpoche acknowledges this source. In assessing Dudjom Rinpoche’s two texts, various aspects of the productive process are highlighted, such as: the ‘blessings’ of a current generation high status lama connected with the tradition; the needs of the ritual community for familiar textual structures and liturgies; beautiful metrical verses for chanting; the integration of materials from the broader tantric heritage, but also the preservation of some highly individual elements of the revelation.
