The Eternal Sadguru is the messenger of Paramatma. Brahma Vidya (the Divine Wisdom) emanates from Him and he is the Lord of the spiritual domain. In the beginning of the creation, he is sent by the Supreme Being into the world with the light of spiritual knowledge. His only mission is to awaken the suffering souls of the world from the sleepy state of ignorance by shedding upon them the divine light. He liberates the craving and deserving souls from the bondage of Prakriti and enables them to enjoy the nectarine bliss of the Supreme Being. When the current of the spiritual knowledge of the Eternal Guru flows in the soul of a human being, the status of Rishi or Maharshi is attained. The knowledge of Brahma Vidya or Vihangam Yoga, which is found in the Veda the Upanishads, and other holy books is solely due to him. He has been addressed as Sukrit Deo, Atri, Jyoti, Aj and the Sanatan in the Vedas. He has also been mentioned in the Upanishads as Amanava Purusha (Super human being). The Eternal Sadguru sermonize the spiritual practitioners and the real devotees in his manifested or un-manifested form. He can take a human form when he wills.
