Early childhood education in ancient India is closely related to caste system and religious theology, among which the core task of Brahmanism education is to maintain caste oppression system and cultivate Brahmanism religious consciousness. The corresponding implementation of Brahmanism preschool education is carried out in their respective families. Buddhist education plays an important role in the history of Indian education. Its early childhood education can be divided into family education and temple buddhist nun education, but both of them have the characteristics of believing in Buddhism, practicing hard, observing education and being passive and world-weary. Therefore, early childhood education in ancient India has always been based on strong theological preaching.
