*mārkaṇḍeya uvāca
aśraddheyaṃ na vaktavyaṃ pratyakṣamapi yadbhavet
narasyāśraddadhānasya pāpopahatacetasaḥ //

Mârkaṇḍeya said:—Anything in which faith cannot be put, should not be uttered, even if it is based on the direct perception of a person without faith and whose mind is vitiated by sin.—6. Those who are faithless, unchaste, evil minded and wicked, are great sinners, (You must have some sin) that is why you have said so. Now hear the greatness of Prayâga, which I shall tell you as I have heard and seen it directly or indirectly. Whatever else is seen, heard or not seen should be clear to you, if you meditate on them with concentration, taking the Sâstras as your ground of evidence.—7-9.
