History of Dharmashastra (Ancient and Mediaeval Religious and Civil Law in India) v5.c71.s1.51

v5.c71.s1.51

The above statement about the classification of sins and their inclusion among the several classes or grades of sins will show that among the early sūtra works there was no general agreement about the nature and number of mahāpātakas, upapātakas and other classes of sins, even though as early as the Chāndogya Upanisad the mortal sins had been declared to be five. It must be supposed that that Upanisad represented only one school of thought in the times of Āp., Baud. and Gaut, who did not entirely accept the tradition of that Upanisad, but followed other divergent ideas. It is impossible to suppose that the verse quoted in that Upanisad is later than the Dharmasūtras of Āp., Gaut, Baud, and Vas
