There is a school of Buddhism for virtually every view one may have.
For the “all is mind” people there is Yogacara, Zen, and plenty of others.
For the “nothing exists” people there is Madhyamaka and others.
For the “we have souls and want to live forever” people there are Tathatagharba focused schools that interpret that teaching as such, Pure Land, and others.
And so on.
Yet, for some reason all of them are found on almost every Theravada discussion group.
Why is this?
It’s entirely because Theravada is generally agreed upon to be the currently existing school with the most direct connection to the historical Buddha.Thus, it has a draw of authenticity no other school does. So, people who would otherwise be on a Mahayana forum are here, where they overlay their non Theravada views onto Theravada scripture. I am certain most don’t realize this, but it’s quite clearly the case.
I’m old enough to remember when Zen was all the rage, and other Mahayana schools, and Theravada was considered archaic or simply unknown by many. The wild, riddling, exciting Mahayana teachings and iconoclast teachers were seen as the ideal schools to get into.
Then the internet happened and became widely available and full of information over time. It connected people all over the world with scholarly information and suddenly we all were aware that the Mahayana teachings have no direct connection to the historical Buddha, and only Theravada does. And, boom! Theravada is hot. And suddenly all Mahayana views are apparently within Theravada! Previously rare, niche views within Theravada are now extremely common. Anywhere you look you find plenty of Theravadins that believe things that, 50 years ago, would have been extremely rare among Theravadins.
To be clear this is not any negative statement against other schools nor people who like them. This is about human nature and desire for authenticity. I should know the process, I was one of these people, and I certainly don’t feel negative about myself over it. I was into Zen, and other Mahayana schools, then discovered Theravada, overlayed Mahayana onto it, and finally realized what I was doing and became Classical Theravada. Even where I still may be interested in non Classical Theravada ideas I am very careful to not lump them together.
For the rest who weren’t consciously aware of this process it still influenced them. They sincerely don’t even see that they’re overlaying non Theravada ideas onto the school and probably never will. They believe that Theravada really does teach that all is mind and we have souls/eternal consciousness, nothing exists, or whatever. They believe there is zero influence on them from Mahayana. And that’s fine. But the sheer odds that this is true are infinitesimally low. It would be a profound coincidence for them to somehow have a view that is unique among Theravada (at least traditionally), and identical to Mahayana, without any influence at all. There, of course, are exceptions. Some believe in souls/eternal consciousness due to unrelated religions or philosophies, and an extremely rare few surely believe in these things for other reasons. But, the vast majority are influenced by Mahayana in some way or another and drawn to Theravada with these Mahayana views in tow due to Theravada’s unparalleled claim to authenticity.
Something similar actually has already happened with Zen and Mahayana itself. When we look at older books about Buddhism and see that many do shoehorn ideas onto Zen that are entirely foreign to it. It became a catch all for whatever people wanted to jam into it. “Zen and the art of golf, business, negotiation,” and many others were everywhere back when Zen was hot. It was also combined with theism, and plenty of other things.
It would happen to any school. If some other school, like Huayan, for example, was agreed upon by modern scholarship to be the school most historically likely to be directly connected to the Buddha then that school would be the one that people from unrelated traditions would flock to. They would then reinterpret its teachings to be about their own personal positions, and those from other schools. For example, in this alternate reality, a previous Theravadin might go to a forum for Huayan. They would declare that they are Huayan and that Huayan teachings support a down to earth, realist position. They would claim that, bafflingly, and inexplicably, even the Huayan teachings that say, “All is mind” don’t mean that. Rather, they mean, “All is not mind,” and support a realist worldview. They would reinterpret Huayan teachings about Nirvana to be identical to Theravada Nibbana, and so on. And all the while the traditional Huayan people would be bewildered by these bizarre views.
However, it is not bewildering when we see it for what it is: natural human tendency to seek authenticity and inability to let go of views not found in the authentic source.
It’s people thinking, consciously or unconsciously, “I have this view. It agrees 100% with school A. However the authentic school, school B, doesn’t have this. I want to be within the authentic school. Wait, if I look at it like this then it IS in the authentic school B!” Then it snowballs as others do the same.
