My Dear Hayagriva,
So far your opening a center, in the Columbus University, that is also very nice idea. The three days you will be there must be utilized in propagating our Krishna Consciousness amongst the students, and I think in charge of that center, Pradyumna may be left so that when you are there, he will work with you. And when you are not there, he will take care of the center. I think you will like this idea. In this way, Kirtanananda may develop New Vrindaban. He will have a nice assistant, Vamanadeva, and Hrsikesa, and I think everything will come out very successful without delay. Krishna is giving you intelligence and bestowing His Mercy upon you; continue this attitude, whenever you feel some difficulty, chant Hare Krishna. Pray to Krishna to help you, and there will be no difficulty. Be rest assured. I hope this will find you in good health and cheerfulness.
Your ever well-wisher,
A.C. Bhaktivedanta Swami
