This volume is a Festschrift in honour of Professor Marek Mejor’s over forty years of remarkable contributions as a researcher in the field of Indian, Tibetan, and Buddhist studies, as well as a teacher, supervisor, organizer, and a vigorous participant in the scientific community, both in his native Poland and abroad. Edited by Marek Mejor’s long-time colleagues and former students, Guruparamparā brings together a broad range of international scholars, whose learned essays reflect the vast diversity of Marek Mejor’s research interests: from textual studies and philology through religious and philosophical thought to history of Oriental Studies. The resulting anthology will also be of interest to researchers beyond those personally acquainted with the honouree.
