Mbh 13.134.2

"'"Vishnu said, 'That person who, endued with faith and freed from malice, listens every day with concentrated attention to the mysteries in respect of religion and duty that are preserved by the high-souled deities and those mysteries also of the same kind that are preserved by the Rishis, has never to succumb to any evil. Such a person becomes also freed from every fear. That man who, with his senses under thorough control, reads these sections which treat of these auspicious and meritorious duties, together with their mysteries,--duties that have been declared (by the previous speakers), acquires all the merits that attach to their actual performance. Sin can never overmaster him. Verily, such a man can never be stained with faults of any kind. Indeed, one wins abundant merits by reading these mysteries (as declared), or by reciting them to others, or by hearing them recited. The deities and the Pitris eat forever the Havya and the Kavya offered by such a creature. Both these, in consequence of the virtues of the offerer become inexhaustible. Even such is the merit that attaches to the person who, with concentrated attention, recites these mysteries to foremost of Brahmanas on days of the full moon or the new moon. Such a person, in consequence of such an act, becomes steady in the observance of all duties. Beauty of form and prosperity also become his. He succeeds, besides this, in becoming the favourite, for all time, of the Rishis and the deities and the Pitris. If a person becomes guilty of all sins save those which are classed as grave or heinous, he becomes cleansed of them all by only listening to the recitation of these mysteries about religion and duty.'"
