The India of ancient ages (at least 8000 - 30000+ BC) has been known to be different than what we are today. Possibly the continuity was there till the Gupta Dynasty, though some decaying was already there as is evident from the mention of caste by Buddha.

However we did not hear about much of the attributes related to this civilization like sati, child marriage, gunghat, lower position of women in society, etc. Also there is a big gap in the knowledge level, way of education, societal development, etc.

Where has the discontinuity crept in and led to this major downfall ?

How to arrest this downfall ?

Love and best wishes
