SB 3.19.37
yo vai hiranyaksa-vadham mahadbhutam
vikriditam karana-sukaratmanah
srnoti gayaty anumodate ’ñjasa
vimucyate brahma-vadhad api dvijah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O brahmanas, anyone who hears, chants, or takes pleasure in the wonderful narration of the killing of the Hiranyaksa demon by the Lord, who appeared as the first boar in order to deliver the world, is at once relieved of the results of sinful activities, even the killing of a brahmana.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Since the Personality of Godhead is in the absolute position, there is no difference between His pastimes and His personality. Anyone who hears about the pastimes of the Lord associates with the Lord directly, and one who associates directly with the Lord is certainly freed from all sinful activities, even to the extent of the killing of a brahmana, which is considered the most sinful activity in the material world. One should be very eager to hear about the activities of the Lord from the bona fide source, the pure devotee. If one simply gives aural reception to the narration and accepts the glories of the Lord, then he is qualified. The impersonalist philosophers cannot understand the activities of the Lord. They think that all His activities are maya; therefore they are called Mayavadis. Since everything to them is maya, these narrations are not for them. Some impersonalists are reluctant to hear Srimad-Bhagavatam, although many of them are now taking an interest in it just for monetary gain. Actually, however, they have no faith. On the contrary, they describe it in their own way. We should therefore not hear from the Mayavadis. We have to hear from Suta Gosvami or Maitreya, who actually present the narrations as they are, and only then can we relish the pastimes of the Lord; otherwise the effects on the neophyte audience will be poisonous.
