There were many significant developments upto about the 3rd century A.D. the most important being the code of Manu.The Mahagana scripture of this period ( Saddharma Pundarika) is known to be a parallel to the Bhagavad-Gita. A number of Puranas were written. The religion of Upanisads was thus made simple for the understanding of the common people and was more widely accepted. This can be seen as a reaction to the Buddhist fanaticism . The six schools of philosophy emerged distinctly. The famous literature of this age include Patanjali's Mahabhasya and Bharata's Natyasasta.( to be cont------d).
