Peter Felix Barth, known also as Lama Thapkhay, was born in 1956 and is an American author focusing on the mind teachings of Tibetan Buddhism. His background includes physics, engineering, and education, having served as an adjunct professor. Barth traveled to India in 1974 to study meditation under Tibetan Buddhist lamas, receiving lay ordination and completing preliminary Mahamudra studies. He later pursued physics in the United States, earning degrees and conducting research on neural networks and the Ising model. His academic career included teaching Information Systems Management at the University of San Francisco. As a Buddhist writer, Barth has authored comprehensive guides on Mahamudra and Dzogchen practices, some of which have received significant recognition, including being recommended by Library Journal and included on a reading list by Traleg Kyabgon Rinpoche. He founded the Mahamudra Meditation Center in 1990, dedicated to the instruction of Mahamudra and Dzogchen. Barth retired from his professional careers in 2015.

Peter Felix Barth has made significant contributions to the understanding of Tibetan Buddhist meditation, particularly Mahamudra and Dzogchen. His early studies in India under Kagyu and Nyingma lamas provided a foundation for his later work. Inspired by texts like "Moonbeams of Mahamudra" and oral instructions from teachers such as Thrangu Rinpoche, Barth authored "Piercing the Autumn Sky: Discovering the Natural Freedom of Mind." This work, initially self-published, gained wider recognition through professional translation and forewords by prominent Rinpoches. Library Journal described it as "perhaps the most accessible book of the Tibetan tradition." Barth also produced detailed meditation manuals for advanced Kagyu and Nyingma practices, serving as guides to classical texts. He further edited "Mahamudra Teachings" by Garchen Rinpoche, focusing on Drikung Kagyu lineage teachings.

Beyond his work in Buddhist studies, Peter Felix Barth possesses a strong academic background in physics and engineering. He earned B.S. and M.S. degrees in Physics, with his master's thesis exploring solutions to the Ising model for neural networks. This scientific research led to published works on theoretical models. Barth also served as an adjunct professor in Information Systems Management at the University of San Francisco from 1997 to 2008. In 1990, he founded the Mahamudra Meditation Center, a non-profit organization dedicated to Mahamudra and Dzogchen practices, which operated until 2011. He also received Zen precepts in 1990. Since 1998, he has been listed as "Lama Thapkhay" on the official website of the 17th Karmapa.
