All these points are so obvious that anyone who says that Hinduism is as foreign to India as Islam or Christianity, deserves to have his head examined. The followers of both Islam and Christianity have full knowledge of and pride in the time and place of origin of their religions outside India, the early history of their religions outside India, the arrival of their religions into India (brought in by invaders and imperialists), and the manner in which their religions were established in India. On the other hand, until the Aryan invasion theory was mooted by the European imperialists, no Hindu had ever suspected that any foreign connection could be attributed to his religion. Even today, with the Aryan invasion theory being instilled into every Hindu brain right from childhood, no Hindu worth his salt would accept the contention that Hinduism is of foreign origin.
