Please accept my blessings. I beg to acknowledge receipt of your letter dated July 13, 1974 and have noted the contents carefully. Yes, a shiksa guru is anyone who can give spiritual advancement. You take instruction from my books, and if you are unable to understand any portion of the books, then you can get it explained by any senior devotee, whether Madhukanta or anyone else. Any senior devotee can be an instructor in spiritual subject matters. If you like to take instruction from Madhukanta, there is no harm.
I hope this meets you in good health.
