The original Bharata and modern India are not the same. The original Bharata means the whole earthly planet. Gradually being sectioned, the modern India is only a fractional part of the original Bharata. So the knowledge is distributed in so many departmental Vedic knowledge, but the whole process is aiming at God-realization.
The living entities within this material world are supposed to be rebellious conditioned souls who disregarded the order of the Supreme Lord, and they lost their spiritual kingdom. It is something like Milton's idea of "Paradise Lost." This material world is created, developed, maintained, produces many by-products, then gradually dwindles, and at last it is dissolved or annihilated. The spirit souls or living beings, are by nature eternal. This condition of life for the living beings are by nature eternal. This condition of life for the living beings, namely to go through repeated births and deaths, is unnatural for him. Therefore the whole Vedic knowledge is devised to regulate the life of the living entities not in the animal form of life, but in the human form of life, so that he can fulfill his material desires, but at the same time he becomes elevated to his original spiritual position. This process of evolution from the lowest aquatic life up to the stage of brahminical culture is delineated in the whole Vedas. This is called knowledge, and when one is liberated from the material contamination, the same knowledge further advanced becomes transcendental knowledge.
