Swami Mukundananda tells us in this lecture about the importance of a Guru.
He says that it is the Guru who will reveal to us the divine knowledge of God. Without having correct understanding of the philosophy, an individual soul cannot move forward in the spiritual path. Only a Guru will teach us how to do spiritual practice and guide us in the path of God-realization by removing all the doubts that arise in our minds, so that we progress speedily in our path.
The Guru will impart all the scriptural knowledge. He will teach you who is God? How does God look? How to reach him? He will explain all the required knowledge. Only a guru can make a soul a God-realized one.
