More proof for not changing the books

Prabhupāda: You can show Bhagavad-gītā.
Gopāla Kṛṣṇa: A very authoritative presentation. For example, here’s the original Sanskrit śloka, word for word…Guest (3): For example, sāṅkhya-yoga. You have a separate book? Then sthita-prajñā. You have a separate…?Prabhupāda: No separately. It is there in the Bhagavad-gītā.Guest (3): But that way, your volumes are dealing with each chapter of Gītā?Prabhupāda: Yes.Gopāla Kṛṣṇa: Each śloka. Each chapter.Guest (2): No, no. Not inside the book. Different volumes. Like eighteen chapters, but eighteen volumes.Prabhupāda: No, no.Gopāla Kṛṣṇa: No. It’s in one book. Twelve hundred pagesGuest (3): And the interpretation is by you yourself?Prabhupāda: Yes. Not interpretation. I am explaining as it is. You can read one.Guest (3): Have you tried to compare with Gītā written by Gyaneshvara, or by Vinoba Bhave or by somebody else?Prabhupāda: According to Bhagavad-gītā, if you don’t follow the instruction of Bhagavad-gītā, you may be very learned scholar, whatever you write, it is lost. We follow that principle. As stated in the Bhagavad-gītā, evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). Find out this Fourth Chapter.Guest (2): Have these books been reviewed in foreign papers?Prabhupāda: It is very widely read.Gopāla Kṛṣṇa: For example, in the Fourth Chapter Lord Kṛṣṇa says,evaṁ paramparā-prāptamimaṁ rājarṣayo viduḥsa kāleneha mahatāyogo naṣṭaḥ parantapa(BG 4.2)Prabhupāda: Kṛṣṇa says that this Bhagavad-gītā has to be received by the disciplic succession. And sa kālena yogo naṣṭaḥ parantapa. Because that disciplic succession is now broken, that yoga system is now lost. So all these interpreters, they are interpreting in their own way. Therefore it is lost. So there is no use of consulting this lost version.Guest (3): So you just give it as it is.Prabhupāda: That is… Therefore my Bhagavad-gītā is named Bhagavad-gītā As It Is.No interpretation.Gopāla Kṛṣṇa: Each word is the original Sanskrit śloka, English transliteration, word by word meaning, so there’s no room for manipulation. There’s a translation and purport. Every book that Śrīla Prabhupāda has written has the same format and each book is illustrated.[Room conversation, December 29,1976, Bombay]
