Disciplic succession: the key to understand the scriptures
All conditioned souls share the same four defects. Due to these intrinsic defects, perfect knowledge can't be produced inside this material world, it has has to be imported from outside the universe.

All conditioned souls share the same four defects. We are propense to commit mistakes, to be Illusioned, to cheat others and the very senses we use to obtain knowledge are imperfect. Due to these intrinsic defects, perfect knowledge can't be produced inside this material world. We may create theories, and sometimes we may get certain things right, but our knowledge will never be complete or perfect. Perfect knowledge has to be imported, to come from outside this dark universe.
In the 4th chapter of the Gita, Krsna reveals how in the past He had explained this transcendental science to Vivasvān, the demigod presiding over the sun, and that He was again transmitting the same transcendental knowledge to Arjuna. When Arjuna questions how He could have spoken to Vivasvān millions of years ago, Krsna reveals that He comes regularly to reveal the transcendental science whenever this transcendental knowledge becomes lost. As He mentions: "Whenever and wherever there is a decline in religious practice, O descendant of Bharata, and a predominant rise of irreligion – at that time I descend Myself." (Bg. 4.7)
Just as Krsna comes personally, He also regularly sends His pure devotees to reveal the same spiritual knowledge. Pure devotees share the same pure and transcendental nature as Krsna, and therefore they can reveal the same perfect knowledge. In this way, sometimes Krsna comes personally, and sometimes He sends his perfect representatives from the transcendental realm to deliver us perfect knowledge.
Once revealed inside the universe, the knowledge is carefully transmitted through a disciplic succession that maintains the conclusions of the text. One who is now a disciple has the duty of properly learning this knowledge and later transmitting it to his or her students without adulteration. The form may change, as the knowledge is explained according to the mentality of different audiences, but the essence must be maintained. Because the original knowledge is already perfect, there is no space for improvement. Any change just degrades the message, just like one will never make any improvement in a supercar by hitting it with a sledgehammer.
As long as one remains faithful to the conclusions of the previous links of the chain, the knowledge is preserved. But as soon as there is change, the knowledge is lost, and the branch withers. Krsna always makes sure that at least some of the branches of the tree remain, generation after generation. If at a certain point, all branches are lost, He comes again or sends His representative to make a new revelation. In this way, this knowledge remains available generation after generation to sincere seekers.
As Srila Prabhupada explains in his introduction: "Vedic knowledge is not a question of research. Our research work is imperfect because we are researching things with imperfect senses. We have to accept perfect knowledge which comes down, as is stated in Bhagavad-gītā, by the paramparā (disciplic succession). We have to receive knowledge from the proper source in disciplic succession beginning with the supreme spiritual master, the Lord Himself, and handed down to a succession of spiritual masters. Arjuna, the student who took lessons from Lord Śrī Kṛṣṇa, accepts everything that He says without contradicting Him. One is not allowed to accept one portion of Bhagavad-gītā and not another. No. We must accept Bhagavad-gītā without interpretation, without deletion and without our own whimsical participation in the matter. The Gītā should be taken as the most perfect presentation of Vedic knowledge. Vedic knowledge is received from transcendental sources, and the first words were spoken by the Lord Himself."
The Vedic knowledge was originally transmitted from Krsna to Brahma, the creator of this particular universe. At the beginning of the current cycle of creation, Brahma meditated for a thousand years of the demigods, and as a result, he had the opportunity to personally meet the Lord, who revealed the Vedic knowledge to him and granted him a vision of His eternal abode. Brahma in turn transmitted this knowledge to his son, Nārada Muni, who in turn transmitted it to Vyāsadeva, the compiler of the Vedas. Vyāsadeva became also one of the links in the disciplic succession of the Bhagavad-gītā and the compiler of the book. The text that we have access now are the words of Vyāsadeva, who narrates the conversation of Sañjaya and Dhṛtarāṣṭra.
Vyāsadeva in turn transmitted this knowledge to Madhvācārya, who transmitted it to Padmanābha, starting a succession that continues up to this day. At the end of his introduction, Srila Prabhupada gives the complete Paramparā, starting from Krsna, all the way to himself. Srila Prabhupada in turn continued the disciplic succession by teaching his disciples, and they in turn are teaching their own disciples. Srila Prabhupada thus became a large branch of the tree, connecting us to it in the form of branches and leaves.
This transcendental knowledge was originally secret, transmitted by a spiritual master to his trusted disciples, but Srila Prabhupada, and before Him his spiritual master, Srila Bhaktisiddhānta Sarasvatī Thākura, and his father, Srila Bhaktivinoda Thākura, opened it to a wider audience, by writing and publishing numerous books.
Srila Prabhupada called his commentary on the Gita "The Bhagavad-gītā As It Is" because this is a commentary that reveals the original meanings of the text, as received from the disciplic succession, different from other commentaries where the authors give their personal conclusions. In this way, he gave the worldwide audience the possibility of learning the proper conclusions of the Bhagavad-gītā, as explained by Krsna Himself to Arjuna.
Anyone who studies the Bhagavad-gītā by accepting the conclusions Prabhupada gives in his commentary becomes unofficially connected to the Paramparā, although for better results one should study it under the guidance of one of his disciples, grand-disciples, or grand-grand-disciples, who can help him to perfectly understand this perfect transcendental knowledge.
