Upanishads [Upaniszady], tr. Marta Kudelska, Wydawnictwo Oficyna Literacka, Kraków 1998.

Upanishads constitute the collection of the most significant philosophical and religious texts concluding the Vedic tradition. As such they contain a message that is significant for the later classical philosophical thought of India composed in Sanskrit and translated into almost every language on earth. The present edition is the first Polish translation of all thirteen classical Upanishads. This edition is preceded by a lengthy introduction.
In 1999 the book was awarded with the prize of the Prime Minister of Poland for the outstanding scientific research.
