completed a Doctorate of Philosophy in Oriental Studies (Sanskrit) at Oxford University under the Supervision of Professor Alexis Sanderson (2013). He has been dedicated to the study of Sanskrit and the practice of yoga since 1996. As a scholar of yoga, his special interest is in the medieval yoga traditions of India, particularly those known as Ha_ha and the R_jayoga. JasonÕs thesis is a critical edition and annotated translation of a Sanskrit yoga text called the Amanaska, which is the earliest extant work on R_jayoga. It teaches the attainment of a profound meditative state called Sam_dhi and its methods and terminology are largely derived from Tantric _aivism. Copies of seventy manuscripts of the
Êwere acquired from more than twenty five libraries in India and Nepal. The critical edition was established on stemmatic analysis of the manuscripts, a case-by-case examination of the variant readings and the use of parallel passages derived from an extensive survey of mediaeval yoga texts. This philological work became the basis for a reconstruction of mediaeval yoga's broader history from the twelfth to fifteenth century, which constitutes the main part of the monographic introduction to the edition. In addition to documenting the mediaeval history of R_jayoga for the first time, Jason's doctoral research had significant implications on the history of modern yoga. In tracing R_jayoga's roots to Tantric _aivism, his research revealed that the relationship between R_jayoga and the Yogas_tras was a late nineteenth-century development. In his article forÊ
Ê(2013), this finding served as the basis for a broader discussion on how yoga lineages use tradition to sanction innovation, resulting in many competing interpretations of exemplars such as R_jayoga. Owing to the interdependence of Ha_ha and R_jayoga traditions, Jason's doctoral research identified the earliest definition of Ha_hayoga in a commentary on a Buddhist Tantra. His discussion of this and a new interpretation of the meaning of the term 'ha_ha' in Ha_hayoga was published in a paper byÊ
Ê(2011). Since the late nineteenth century, Indologists have understood Ha_hayoga as a yoga performed by ÔforcefulÕ exertion, whereas the textual evidence suggests that it was a type of yoga which ÔforcedÕ (ha_ha) certain results. During his doctoral fieldwork in India, he discovered the earliest textual source for a list of more than eight four yoga postures. This is the subject for a forthcoming publication in which new manuscript evidence proves that some traditions of Ha_hayoga incorporated the practice of many dynamic postures before the British took control of India. Jason's articles have been quoted in recent publications on yoga, such as James Mallinson's academic journal articles on Ha_hayoga, Mark Singleton'sÊ
