October 31, 1969
My Dear Dinesh,
Please accept my blessings. I beg to thank you for your letter dated October 21, 1969 along with a contribution of $25. I have already acknowledged receipt of your new record. Regarding the disciplic succession coming from Arjuna, disciplic succession does not always mean that one has to be initiated officially. Disciplic succession means to accept the disciplic conclusion. Arjuna was a disciple of Krishna and Brahma was also a disciple of Krishna. Thus there is no disagreement between the conclusions of Brahma and Arjuna. Vyasadeva is in the disciplic succession of Brahma. The teachings to Arjuna was recorded by Vyasadeva verbatim. So according to the axiomatic truth, things equal to one another are equal to each other. We are not exactly directly from Vyasadeva, but our Gurudeva is a representative of Vyasadeva. Because Vyasadeva and Arjuna are of equal status, being students of Krishna, therefore we are in the disciplic succession of Arjuna. Things equal to the same thing are equal to one another.
Regarding your second question about Sanjaya, he was a student of Vyasadeva, and by the mercy of Vyasadeva he was able to receive the message of the conversation of Krishna-Arjuna. Thus Sanjaya was able to speak to Dhrtarastra about the conversation on the Battlefield of Kuruksetra. Regarding your final question, the marginal potency means internal potency. But because the marginal potency sometimes comes within the external position, therefore, in spite of its being internal potency it is turned to marginal potency. This is stated in Visnu Purana: Any potency of Krishna is spiritual energy, but due to varieties of actions a section is called marginal potency or external potency.
Please offer my blessings to your good wife, Krishna Devi, and daughter, Visnu Arati. I hope this will meet you all in good health.
Your ever well-wisher,
A.C. Bhaktivedanta Swami
