Srimad Bhagavatam Canto 04, Chapter 30, Text 21

SB 4.30.21

maitreya uvaca
evam bruvanam purusartha-bhajanam
 janardanam prañjalayah pracetasah
tad-darsana-dhvasta-tamo-rajo-mala
 giragrnan gadgadaya suhrttamam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The great sage Maitreya said: After the Personality of Godhead spoke thus, the Pracetas began to offer Him prayers. The Lord is the bestower of all success in life and is the supreme benefactor. He is also the supreme friend who takes away all miserable conditions experienced by a devotee. In a faltering voice, due to ecstasy, the Pracetas began to offer prayers. They were purified by the presence of the Lord, who was before them face to face.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The Lord is herein described as purusartha-bhajanam, the bestower of the ultimate goal of life. Whatever success we want in life can be attained by the mercy of the Lord. Since the Pracetas had already attained the Lord’s mercy, they were no longer subject to the contamination of the material modes. The material modes dissipated from them just as the darkness of night immediately dissipates when the sun rises. Because the Lord appeared before them, naturally all the contaminations of the material qualities of rajas and tamas completely disappeared. Similarly, when an unalloyed devotee chants the Hare Krsna maha-mantra, he is also purified of all material contamination because the name of the Lord and the Lord are identical. As stated in Srimad-Bhagavatam (1.2.17):
 
srnvatam sva-kathah krsnah
 punya-sravana-kirtanah
hrdy antah-stho hy abhadrani
 vidhunoti suhrt satam
 
“Sri Krsna, the Personality of Godhead, who is the Paramatma [Supersoul] in everyone’s heart and the benefactor of the truthful devotee, cleanses desire for material enjoyment from the heart of the devotee who has developed the urge to hear His messages, which are in themselves virtuous when properly heard and chanted.”
 
The holy name of the Lord is the Lord Himself. If one chants and hears, he becomes purified. Gradually all material contamination disappears. The Pracetas were already purified due to the Lord’s presence before them, and they could therefore offer the proper prayers with folded hands. In other words, as soon as devotees are engaged in devotional service, they become transcendental to all material contamination immediately, as confirmed in Bhagavad-gita (sa gunan samatityaitan brahma-bhuyaya kalpate). Sometimes the devotees are dissatisfied due to their not seeing the Supreme Personality of Godhead personally. When the Pracetas saw the Supreme Lord personally present, their unhappiness vanished.
