Sri Anirvan wrote almost exclusively in Bengali and only occasionally in English. This is a collection of all his English writings except his letters which he wrote to his Western and non-Bengali friends and disciples. The present volume contains nine essays, the first on Buddhiyoga being the most considerable. In these essays, Sri Anirvan covers a wide area and touches upon most of the salient points of Hindu spirituality, direct and indirectly. He roams through the vast territory of Hindu philosophical and theosophical thought with ease and familiarity.
