Śrīmad-Bhāgavatam
[Canto 4, Ch. 30]
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 Pracetās began to offer prayers. They were purified by the presence of the Lord, who was before them face to face.
PURPORT
The Lord is herein described as  puruṣārtha-bhājanam  (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 Pracetās 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  Kṛṣṇa mahā-mantra , he is also purified of all material contamination because the name of the Lord and the Lord are identical. As stated in  Śrīmad-Bhāgavatam :
śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ 
  puṇya-śravaṇa-kīrtanaḥ 
  hṛdy antaḥ-stho hy abhadrāṇi 
  vidhunoti suhṛt satām
“Śrī Kṛṣṇa, the Personality of Godhead, who is the Paramātmā [Supersoul] in everyone's heart and the benefactor of the truthful devotee, cleanses desire for material enjoyment from the heart of the devotee who relishes his messages, which are in themselves virtuous when properly heard and chanted.” ( Bhāg.  1.2.17)
The holy name of the Lord is the Lord Himself. If one chants and hears, he becomes purified. Gradually all material contamination disappears. The Pracetās 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-gītā :
māṁ ca yo 'vyabhicāreṇa 
  bhakti-yogena sevate 
  sa guṇān samatītyaitān 
  brahma-bhūyāya kalpate
