Spirtual Master is eternal

[That's me in the far background]

Madhudvisa: Is there any way for a Christian to do without the help of a Spiritual Master. To reach the spiritual sky through believing the words of Jesus Christ and trying to follow his teachings?
Srila Prabhupada: I don't follow.
Tamala Krishna: Can a Christian in this age, without a Spiritual Master, but by reading the Bible, and following Jesus"s words, reach the ...
Srila Prabhupada: When you read the Bible, you follow the Spiritual Master. How can you say without. As soon as you read the Bible, that means you are following the instruction of Lord Jesus Christ. That means that you are following the Spiritual Master. So where is the opportunity of being without Spiritual Master.
Madhudvisa: I was referring to a living Spiritual Master.
Srila Prabhupada:
Spiritual Master is not question of ... Spiritual Master is eternal...so your question is "without Spiritual Master". Without Spiritual Master you cannot be at any stage of your life. You may accept this Spiritual master or that Spiritual master. That is a different thing. But you have to accept. As you say that "by reading Bible", when you read Bible that means you are following the Spiritual Master represented by some priest or some clergyman in the line of Lord Jesus Christ.
