King Yuddhisthira tells us in KB chp 83
My dear Lord Kṛṣṇa, great personalities and devotees in full Kṛṣṇa consciousness always think of Your lotus feet and remain fully satisfied by drinking the nectar of transcendental bliss. The nectar which they constantly drink sometimes comes out of their mouths and is sprinkled on others as the narration of Your transcendental activities. This nectar coming from the mouth of a devotee is so powerful that if one is fortunate enough to have the opportunity to drink it, he is immediately freed from the continuous journey of birth and death. Our material existence is caused by our forgetfulness of Your personality, but fortunately the darkness of forgetfulness is immediately dissipated if one is privileged to hear about Your glories. Therefore, my dear Lord, where is the possibility of ill fortune for one who is constantly engaged in hearing Your glorious activities?
