"Is there any science that gives us the knowledge by which we may become immortal? Yes, we may become immortal, but not in the material sense. We cannot receive this knowledge in so-called universities. However, there is knowledge contained in the Vedic scriptures by which we may become immortal. That immortality is our better position. No more birth, no more death, no more old age, no more disease. Thus the guru takes on a very great responsibility. He must guide his disciple and enable him to become an eligible candidate for the perfect position -- immortality. The guru must be competent to lead his disciple back home, back to Godhead."
