I find the words "forgery" and "fake" inappropriate, because
1. the Buddhist texts are exactly this, "texts". They are not contracts, nor legal papers, nor do they come with an attached warranty.
2. The words "forgery" and "fake" imply that somebody is disappointed or feels deceived, but by whom? Did he/she pay the good monks/nuns and laymen/laywomen who were so sweet to carry those precious texts through 2500 years to us? Did these monks/nuns and laymen/laywomen promise "you" that they would make no mistake?
3. These texts have gone through wars, earthquakes, genocides, pests, fires and floods. It weren't always the wisest or the most learned monks/nuns, laymen/laywomen who survived. Please be gentle with our good friends who passed away. Maybe they made mistakes. They might have stuck together the wrong palm leaves; they might have added passages they thought somebody had forgotten; maybe they even changed some words they thought somebody else had copied wrongly. Is that faking or forgery? Did you ever try to learn by heart or copy the Abhidhamma Nikaya at > 40° Celsius in a badly lit non-A/C room? Please try!
4. The texts went through a phase of oral transmission. Oral transmission carries the danger that the person memorizing the texts will without willing it, make all similar passages equal, and will also without willing it, replace shorter versions of the same passage with longer versions.
5. The texts went through a phase of palm leaf transmission with all the problems of broken strings and loose leaves. The texts were real leaves in real baskets. Many accidents happened and the persons who tried to repair the accidents often didn't have "another basket" (or a CD) to check whether they were getting the broken sequence or the missing leaves right. Not to speak of insects eating whole words...
6. The texts went through centuries of copying, see 3. above.
I think the historical view is important and can add to our understanding. Unhappily, it will also lead to a lot of unhappiness, because it is a very Western way of thinking, and not acceptable to many traditional Buddhists in Asia. Please be gentle and soft-spoken!
Regarding meditation, I believe it is true that there are some teachers or schools who/which are teaching Vipassana as the only true Buddhist meditation. But the main Theravada Buddhist instruction manual, the "Visuddhimaggo" doesn't limit meditation instructions to this, nor do the meditation teachers at Wat Maha That and many other traditional meditation centers all over Asia.
Finally, we need Sila, Samadhi and Pañña. Sila is more than Vinayo, Samadhi more than Vipassana, and Pañña is much more than Pali. For me, it includes the cool-hearted knowledge that books are only books.
Have a wonderful day!
