Sūta continued: This has Ajñāna as the precondition. Hence, one should avoid ignorance. If any one does not accept the words of sages as authority, nor values good manners and breeding as practised by wise men, if any one is opposed to the discipline of four castes and stages of life and if one is antagonistic towards wise men and scriptural injunctions—that is the path leading to hell,—that is the cause of birth in the lower species of animals.
