The preservation and transmission of cultural heritage was another important aim of education. It was incumbent on the religious teachers to commit their respective sacred books to memory in order to ensure their transmission to unborn generations.

For the preservation of cultural traditions, special methods were adopted. The theory of three debts was propounded. First of all, one owes a debt to gods, and one can liquidate it only by learning how to perform proper sacrifices and by regularly offering them. Religious traditions of the race were thus preserved. Secondly, one owes a debt to Rishis or savants of the bygone ages and one can discharge it only by studying their works and continuing their literary and professional traditions. This enabled one to master and maintain the best literary and professional traditions. The third debt was to ancestors, which could be rapaid only by raising progeny and by imparting proper education to it. There were also practices of Svadhyāya and Rșitarpaņa; the former enjoined a daily recapitulation of at least a portion of what was learnt during student-life and the latter required a daily tribute of gratitude to be paid to the literary giants of the past at the time of daily prayers.
