Some generations ago it was unusual to come across cases of single women India. Particularly in the Hindu society thought it is well recognised that in ancient India women could remain single and serve the society in various capacities. Prof Altekar refers to two types of women, the Brahmavadinis and Sadyovahas. Brahmavadinis did not marry and were lifelong students of theology and philosophy. Sadyovahas pursued studies upto the age of 15 or 16 when they got married. Brahmavadinis used to aim an excellence and did Vedic studies which in later puritanical times was denied to them by orthodox Hindus. It is better to see the horoscope of a girl.
