SB 12.12.49
mrsa giras ta hy asatir asat-katha
na kathyate yad bhagavan adhoksajah
tad eva satyam tad u haiva mangalam
tad eva punyam bhagavad-gunodayam
Translation:
Words that do not describe the transcendental Personality of Godhead but instead deal with temporary matters are simply false and useless. Only those words that manifest the transcendental qualities of the Supreme Lord are actually truthful, auspicious and pious.
Purport:
Sooner or later, all material literature and discussion must fail the test of time. On the other hand, the transcendental descriptions of the Supreme Lord can free us from the bondage of illusion and restore us to our eternal status as loving servants of the Lord. Although men who are like animals may criticize the glorification of the Absolute Truth, those who are civilized should go on vigorously propagating the transcendental glories of the Lord.
