One of Tibetan Buddhism's most influential modernist thinkers is Gendün Chöphel (1903–1951), who, according to Donald S. Lopez Jr., "was arguably the most important Tibetan intellectual of the twentieth century." Gendün Chöphel traveled throughout India with the Indian Buddhist Rahul Sankrityayan and wrote a wide variety of material, including works promoting the importance of modern science to his Tibetan countrymen and also Buddhist philosophical texts such as "Adornment for Nagarjuna’s Thought". Another very influential Tibetan Buddhist modernist was Chögyam Trungpa, whose Shambhala Training was meant to be more suitable to modern Western sensitivities by offering a vision of "secular enlightenment".
