The word sravayet, mentioned in a previous verse, indicates that one should not only read for himself, but should also induce others to read and hear. That is called preaching. Caitanya Mahaprabhu recommended this practice: yare dekha, tare kaha krsna-upadesa (Cc. Madhya 7.128). Whomever you meet, simply talk with him about the instructions given by Krsna or tell him of narrations about Krsna. Prthu Maharajas history of devotional service is as potent as narrations about the activities of the Supreme Personality of Godhead. One should not make distinctions between the pastimes of the Lord and the activities of Prthu Maharaja, and whenever it is possible a devotee should attempt to induce others to hear about Prthu Maharaja. One should not only read of his pastimes for ones own benefit but should induce others to read and hear about them also. In this way everyone can be benefited.
