Aunque basado en enseñanzas milenarias de los lamas tibetanos, Concentración y Contemplación está escrito desde una perspectiva actual, tan rigurosa con el pasado y la tradición como libre de las influencias culturales y abierto a las necesidades y situaciones del mundo contemporáneo.
His Eminence Loden Sherap Dagyab Rinpoche, the 9th Dagyab Kyabgön, is an incarnate lama of the Gelugpa school of Tibetan Buddhism. He directed the Tibet House in New Delhi, 1964–66, worked as a Tibetologist at the Institute for Central Asian Studies of Bonn University, and was a founder of Tibethaus Deutschland in Frankfurt, Germany.
The Kyabgön ("Lord of Protection") tulkus are held to be successive incarnations of Dragpa Gyatso (1572–1638), as well as of the great translator Loden Sherab (1059–1109), and have historically served as spiritual heads of the Dagyab region in Eastern Tibet. Since the 4th Kyabgön of Dagyab, all following reincarnations have additionally held the title Hothogthu Nomonhan, "Noble King of Dharma."
