A series of lectures given by Dulal Chandra dasa on devotional service as presented on Sadhus, Bhagavatam, and more with emphasis on the practice of bhakti yoga. These lectures present knowledge of Krishna Consciousness as taught by Sri Caitanya Mahaprabhu and his illustrious followers, the six goswamis. Dulal Chandra dasa is a direct disciple of His Divine Grace A.C. Bhaktivedanta Swami Prabhupada. Although I lack any personal qualification to lecture on the lofty subject of self realization, this presentation is my humble attempt to repeat what I have heard from my spiritual master and pass it on without adulteration. In this way I hope to serve the desire of my guru and provide you with some gems of transcendental wisdom that will hopefully spark an interest in ending your entanglement in material existence and becoming firmly reestablished in your eternal spiritual position. I present myself before you with a straw between my teeth, begging that you will listen to what is presented here with an open mind and heart. The transcendental wisdom which will be presented here is of the upmost importance for everyone wishing to advance to the topmost platform of spiritual awareness. This knowledge is descending through an unbroken chain of self realized spiritual masters directly from the Supreme Personality of Godhead.
