Talk of kṛṣṇa-kathā, or topics about Lord Kṛṣṇa or His incarnations, is spiritually so inspiring that the reciter and hearer are never exhausted. That is the nature of spiritual talks. We have actually seen that one can never become satiated by hearing the conversations between Vidura and Maitreya. Both of them are devotees, and the more Vidura inquires, the more Maitreya is encouraged to speak. A symptom of spiritual talks is that no one feels tired. Thus upon hearing the questions of Vidura, the great sage Maitreya did not feel disgusted but rather felt encouraged to speak at greater length.
