My dear friends, O sons of the demons, you cannot please the Supreme Personality of Godhead by becoming perfect brahmanas, demigods or great saints or by becoming perfectly good in etiquette or vast learning. None of these qualifications can awaken the pleasure of the Lord. Nor by charity, austerity, sacrifice, cleanliness or vows can one satisfy the Lord. The Lord is pleased only if one has unflinching, unalloyed devotion to Him. Without sincere devotional service, everything is simply a show.
