This volume is a compilation of edited extracts from lectures on Vedanta by Swami Paramarthananda, a respected disciple of Swami Dayananda Sarasvati. Known for his structured teaching of Sri Sankara's tradition, Swamiji's talks explore the core ideas of the Upanishads—non-sectarian, timeless teachings promoting spiritual unity. Compiled by his student Sri R. B. Athreya and originally published in Tattvāloka magazine, the book has seen multiple reprints due to reader interest. It serves as both a refresher for Vedanta students and an introduction for newcomers.
