Your specific duty is to chant and hear the transcendental Name of the Lord, read some passages from my English version of the Srimad-Bhagavatam and Srimad Bhagavad-gita (Gitopanisad) and explain them as far as possible you have heard from me. Any devotee who has developed genuine Love for Krishna can also explain the truth about Krishna because Krishna helps such sincere devotee seated in his heart. Everyone must be frustrated who is not Krishna conscious because the eternal relationship with Krishna is so nice. That eternal relationship with Krishna can be revived simply by chanting His Holy Name in right earnest.
Letter to Dayananda, Nandarani and Uddhava das, 20 September, 1967
