The Rishi and the Brahmacharin
In ancient India, the concept of the Rishi connoted the highest ideal of the teacher. The teacher was a Yogin, one who had realized or was a seeker of true knowledge that comes through the practice of Yoga, which was at that time a developing science and art of psychological concentration and perfection. The Vedic Rishis described their aspirations and victories in the form of Mantra, inevitable expression born out of innermost vision and realization.
The Vedic Rishis refer to their 'forefathers' as great pathfinders, and spoke of them in legends and myths in order to describe what they had achieved.

This breaks the limits of the physical being, which opens out to the Light and is upheld in its new wideness by the infinite Consciousness, mother Aditi, and her sons, the divine powers of the supreme Deva or Lord. This was the meaning of Vedic immortality.
There are also references in the second hymn of the fourth Mandala to the seven divine seers, who are the divine Angirasas and the human fathers. Riks 12 to 15 describe the seven Rishis as the supreme ordainers of the world-sacrifice, and put forth the idea of the human being 'becoming' the seven Rishis, that is to say, creating them in himself and growing into that which they mean, just as he becomes the Heaven and Earth and the other gods; or,
