"What is this alone? Vaisnava is never alone. When I first came to the United States I was seemingly alone for one year. But I never felt alone. I always felt the presence of my Guru Maharaja. Myself, I was cooking, I was printing books, I was selling books, everything seemingly alone. But I did not lose my determination. Actually you should know this, you are never alone."
(Srila Prabhupada Letter, December 27, 1974)
"You are doing solid work, even alone, and I am very pleased. This is the test for a sincere devotee. Simply by depending on the mercy of the Lord and carrying out the order of the spiritual master, one's success in spiritual life is guaranteed."
(Srila Prabhupada Letter, November 4, 1975)
"So far I am concerned I always take risk for Krishna. I came here in your country risking my life. And still although I am physically unfit, I am trying to execute the orders of my Guru Maharaja as far as possible. So to take risk for Krishna is very good. You know the history of my starting the society in 1966, it was all risky, and I was alone, but I took it depending on Krishna."
(Srila Prabhupada Letter, February 12, 1968)
"You write that you have desire to avail of my association again, but why do you forget that you are always in association with me? When you are helping my missionary activities I am always thinking of you and you are always thinking of me. That is real association. Just like I always think of my Guru Maharaja every moment, although He is not physically present, and because I am trying to serve Him to my best capacity, I am sure He is helping me by His spiritual blessings. So there are two kinds of association: physical and preceptorial. Physical association is not so important as preceptorial association."
(Srila Prabhupada Letter, August 17, 1969)
"We are not separated actually. There are two — vani or vapu. So vapu is physical presence and vani is presence by the vibration, but they are all the same. So Krsna when He was physically present before Arjuna is the same when He is present before us by His vani of Bhagavad-gita. So far I am concerned, I do not factually feel any separation from my Spiritual Master because I am trying to serve Him according to His desire. That should be the motto."
(Srila Prabhupada Letter, June 22, 1970)
