Prabhupāda: Janme janme prabhu sei. Spiritual master who has opened the eyes, he is, spiritual master, the life of the disciple. Do not... He cannot be envied. Janme janme prabhu sei. Life of the disciple. Cakhu-dān dilo jei, janme janme prabhu sei. Nobody can repay the indebtedness of spiritual master, even by getting a duration of life like Brahmā.
