While I appreciate that people likely have been able to fully or close to fully memorize completely and exactly the Vedas, someone having done so is in no way definitive proof that the Vedas are in their original form. That someone has done it so perfectly recently is circumstantial evidence regarding whether or not every single meaning in the Vedas is exactly and without error in its originally laid out form. There is no way to truly know, except to have outside knowledge and to carefully analyze whether every single thing said is actually true or not.

An example of this would be in the Bible:

"For the love of money is the root of all evil" - 1 Timothy 6:10 KJV

"For the love of money is a root of all kinds of evil." - 1 Timothy 6:10 NRSV

While this is the Bible, it is a perfect example of how something can be written in a text that is held authoritatively and therefore not sufficiently critically analyzed and accepted at face value. In the King James Version, if the reader does not understand reality sufficiently, and if they hold the text as authoritative, then they will conclude that the love of money is the root of all evil. This is patentably untrue, however, for there are many evils that do not stem from money. Killing in the name of a cause, such as the Crusades, is not rooted in the love of money. However, other translations have much more open language that has a completely different meaning that allows for other loves of other parts of all to be recognizable as roots of evil.

In much the same way, without a sufficient understanding of reality to hinge to while reading Sanskrit, and with only circumstantial evidence that the text is in its original form and no bias has been interjected by humans in the specific choice of exact words (which is so highly unlikely that it arguably has necessarily occurred--even if no where else but in the translations to english), then there is no way of knowing for certain what carries the essence of the original message sufficiently except by looking elsewhere for details and analyzing all the layers of hidden meaning in all the nuances of the text.

What I mean by that is much the same as 1 Timothy 6:10; there is hidden meaning found in looking to several translations because the bias of the translator becomes more readily apparent, which unveils levels of depth to the text that are not there in a single translation. This occurs with translations of all varieties and the Vedas are certainly not exempt. But this adds depth and character and meaning that is hidden beneath the surface, which ultimately makes scriptures of these varieties that much more beautiful as works of art brought about by our distinctly Omnipotent God.

"The Gauḍīya Vaiṣṇava tradition I follow says the name of Kṛṣṇa descends from the spiritual realm. The Vedas say we are in a dream; and often the easiest way to awaken from a dream is by hearing the name of the dreamer."
"In the Padma Purāṇa, it is stated, " The Holy name of Kṛṣṇa is transcendentally blissful. It bestows all spiritual benediction, for it is Kṛṣṇa Himself, the reservoir of all transcendental
mellows. It is not a material name under any condition, and it is as powerful as Kṛṣṇa Himself." It goes on to say the name and form of Kṛṣṇa are identical, although except that the name is more merciful."

My position on this is firmly that the name is powerless next to whom it is referring. Does your name have more power, when spoken, to shape the world around you than you yourself? Or anyone, for that matter? Or is it in the true being of whom the name represents where the power lies? I would respond that this is precisely placing a portion of The All above the rest. A tradition where the power was known to rest in God, regardless of name, but over time became misconstrued that the name itself was what carried the power. This is not reasonable, and I would say is distinctly evidence against the complete accuracy of these sources of information. "As powerful as Krsna Himself."--There is no possibility of this having complete accuracy, and likely is the result of misconstrued information. No name has power, it is just a label. Even if it is a specific label laid out by The All as their own, it still would not contain within it equal power to The All. Did this name create all that is, was, and ever will be? Or did The All, the Being behind the name?

"It's pleasing to Kṛṣṇa to hear His own name said with love, and Kṛṣṇa has explained that He gives knowledge of Himself to those who are devoted to serving Him."

If the Sanskrit text specifically uses the term "He" and "Himself" and these masculine labels throughout, this would call into question the entire origination of the Vedas as a whole. There are distinctly individuals in the book of Genesis who are believed to be "God" and "the devil", but God is everything. This tells us someone was being interpreted as being God, rather than actually being God in the flesh. God in the flesh is Everything, Unlimited, The All. I would suspect that a similar tradition where someone with deep understanding, sufficient as to know themselves to be God (but also to know all else to be God), led to the Vedas by teaching their wisdom and then being misconstrued as literally being God.

Moreover, "those who are devoted to serving Him" is a dangerous line. What does it mean to be devoted and serving--are they allowed to question whether something is true or is this unacceptable? There is simply no way this is accepted or encouraged, and so I would say this is more evidence of misinterpretations propagating throughout the whole of the philosophy. God is Truth and does not require followers to serve without question or to be devoted in their actions to the cause, for all actions serve God. It does not matter what we choose to do, in the end it is precisely servitude to The Infinite God. The thing with God being Truth, though, is we don't need to believe. It doesn't matter what we believe, because it is true. Therefore, it is in our best interest to question and critically analyze this for whether or not it is true since if we do so we will arrive at the conclusion that it is what it is: Truth. But when something is not true at its core, it requires layers upon layers of details placed by devoted followers, forced/encouraged across generations to build up an elaborate picture that the falsehood is hidden beneath.

All in all, the Vedas deserve full consideration, but not without critical analysis and meticulous scrutiny built upon an extensive awareness of as many other sources of information as possible, in order to separate what is true from what is untrue and the depths of meaning carried beneath the surface.
