The Essential Teaching - Upadesh Saar is one of the most popular Vedantic texts.

All spiritual paths lead us to the same goal of Realisation. The four main paths, Path of Action (Karma Yoga), Devotion (Bhakti Yoga), Yoga (Astanga Yoga) and Knowledge (Jnana Yoga) and their common goal are explained beautifully by the great sage of our time, Bhagvan Ramana Maharshi. The words come from the very depth of his own Realisation of the Supreme.

Swami Tejomayananda's commentary further simplifies the profound meaning of the text and brings out its essence in an appealing way.
