“Know that I am eternally your guide, but if you don’t accept me as your guide, what can I do? If my disciples do not take my guidance, what can I do? By bad association it so happens, so I remain silent. I see the pricks of maya …
"You mention that your pathway has become filled with stumbling blocks. But there are no stumbling blocks. I can kick out all those stumbling blocks immediately, provided that you accept my guidance. With one stroke I can kick out all stumbling blocks."
From Srila Prabhupada's Sept 9, 1972 letter to Krsna Das
July 11 1969 letter…You have asked if it is true that the Spiritual Master remains in the material universe until all of His disciples are transferred to the Spiritual Sky. The answer is yes, this is the rule. Therefore, every student should be very much careful not to commit any offense which will be detrimental to this promotion to the Spiritual Kingdom, and thereby the Spiritual Master has to incarnate again to deliver him. This sort of mentality will be a kind of offense to the Spiritual Master. Out of the ten kinds of offenses, the number one offense is to disobey the orders of the Spiritual Master.
The instructions given to the disciple by the Spiritual Master at the time of initiation should be strictly followed. That will make one advance to the spiritual path. But if one deliberately defies such instructions, then his advancement is hampered from the very beginning. This defying means to disconnect the relationship with the Spiritual Master. And anyone who defies and therefore disconnects the relationship with the Spiritual Master can hardly expect the assistance of the Spiritual Master life after life. I hope this will clear up this question sufficiently for you.
Please convey my blessings to the others. I am very pleased that you are working so sincerely to maintain the Montreal temple. Hope this will meet you in good health.
Your ever well-wisher,
A.C. Bhaktivedanta Swami
