Any opinion different from the opinion of the spiritual master is useless. One cannot infiltrate materially concocted ideas into spiritual advancement. That is deviation. CC Adi 12.9 Purport):

Actual text of conversation with Srila Prabhupada in his room, October 18, 1977, Vrndavana, India
Srila Prabhupāda: So, you are taking care of that conveyance?
Tamāla Krnsa: Yes, we are, Śrīla Prabhupāda.
Jayapatākā: Because you are a paramahamsa, Śrīla Prabhupāda, you are seeing everyone else as surrendered to Krsna. But only by your mercy, you are forcing us to serve Krsna.
Srila Prabhupāda: Hare Krsna. One Bengali gentleman has come from New York?
Tamāla Krsna: Yes. Mr. Sukamal Roy Chowdury.
Srila Prabhupāda: So I have deputed some of you to initiate. Hm?
Tamāla Krsna: Yes. Actually… Yes, Śrīla Prabhupāda.
Srila Prabhupāda: So I think Jayapatākā can do that if he likes. I have already deputed. Tell him.
Tamāla Krsna: Yes.
Srila Prabhupāda: So, deputies, Jayapatākā’s name was there?
Bhagavān: It is already on there, Śrīla Prabhupāda. His name was on that list.
Srila Prabhupāda: So I depute him to do this at Māyāpura, and you may go with him. I stop for the time being. Is that all right?
Tamāla Krsna: Stopped doing what, Śrīla Prabhupāda?
Srila Prabhupāda: This initiation. I have deputed the, my disciples. Is it clear or not?
Girirāja: It’s clear.
Srila Prabhupāda: You have got the list of the names?
Tamāla Krsna: Yes, Śrīla Prabhupāda.
Srila Prabhupāda: And if by Krsna’s grace I recover from this condition, then I shall begin again, or I may not be pressed in this condition to initiate. It is not good.
Girirāja: We will explain to him so that he will understand properly.
Srila Prabhupāda: Hm? Hm?
Girirāja: I said we will explain to the Bengali gentleman just as you have described to us, so that he’ll be satisfied with this arrangement.
Srila Prabhupāda: And Dr. Ghosh has his scheme, but actually the scheme is there in the Bhagavad-gītā and Śrīmad-Bhāgavatam. We want to introduce that scheme to our Gurukula. We haven’t got to manufacture scheme. Is that correct?
Girirāja: Yes.
Srila Prabhupāda: Let them learn to rise early in the morning and cleanse. This is the first scheme. This will keep their health nice. Cātur-varnyam mayā srstam [Bhagavad Gita. 4.13]. Unless in the human society the varnāśrama system is introduced, no scheme or social order, health order or any order, political order, will be successful. Bhagavān: Everything is there very clearly in your books, Śrīla Prabhupāda.
Srila Prabhupāda: A man-made scheme-useless. Sāttvika-yuga.(?) What is that verse? Sattvāvalambi-para-sattva-viśuddha-sattvam… From Brahma-samhitā?
