user-1: Ajahn Brahm’s quite interesting position on "too much Dharma" and studying Abhidharma might be conveyed in this citation:

I think of our modern age is that too much Dhamma. So much Dhamma that
you get really confused. So, just keep it easy Four Noble Truths,
Eightfold Path. Keep it simple and if you keep it simple - it [is]
much, much, much easier.
(…)
That gets too much, it gets so much that
people get confused. So, that's reason why they don't get enlightened.
Keep it simple.
(…)
You can actually see that [in Abhidhamma] language - those concepts they didn't arise until a couple of centuries after the time of the Buddha. So, even the language shows you it's much
later.  You know that's great relief you don't have to study all of
that very very difficult stuff. You have to be like a professor to
learn the Abhidharma sometimes. It's so complex. Keep it simple - Four
Noble Truths, Eightfold Path, meditate. That's all the Gunpowder you
need, so keep it going.
Abhidhamma was not taught by the Buddha -- YouTube

Not only Ajahn Brahm, but also Ajahn Sumedho seem to also reduce the Buddhist practise to bare minimum, to repeating “Let go” for the first number years of his practise, which is similar to general teachings of Zen/Chan and experiential Dzogchen approach as well.
Given that obsession is clinging and clinging is suffering - then, truly, for Theravada, Mahayana and Vajrayana, Dharma cannot be realised and experienced merely through reason. Thus, theoretically, sets of teachings might be double edged sword for own progression.
There seems to be common ground in Mahayna with Ajahn Brahm’s claim. Quoting important piece that is a complementary reading to Heart Sutra, a Diamond Cutter sutra:

Moreover, Subhuti, when a bodhisattva practices generosity, he does
not rely on any object—any form, sound, smell, taste, tactile object,
or dharma—to practice generosity. That, Subhuti, is the spirit in
which a bodhisattva practices generosity, not relying on signs. Why?
If a bodhisattva practices generosity without relying on signs, the
happiness that results cannot be conceived of or measured.
(…)
In a place where there is something that can be distinguished by signs, in
that place there is deception. If you can see the signless nature of
signs, you can see the Tathagata.
(...)
Subhuti, a bodhisattva who still depends on notions to practice
generosity is like someone walking in the dark. She will not see
anything. But when a bodhisattva does not depend on notions to
practice generosity, she is like someone with good eyesight walking
under the bright light of the sun. She can see all shapes and colors

We know that Buddha didn’t coin a great deal of technical terms and vocabulary that did arise as attempts of explanation. As such, many things were imputed to Buddha, according to many scholars. The extent of it I don’t dare to bring up as such is not a nature of this post. Yet, we can deduce that most of the practitioners that attained Arahantship in Buddha’s times had in majority followed practical and minimalistic Buddha’s advice. That is at least what Suttas depict intuitively, rather than operating in terse sets of lexical and intellectual frameworks.
In conclusion, several questions arise:

What is the barrier and to what extent do we need to understand things by intellect? Is it not true that just Four Noble truths, a simple teaching, can alone lead us to liberation, quoting Ajahn Brahm?
Is such complexity and variety of modern Dharma why there aren’t more Arahants these times? Because of “Too much Dharma” ? Is this what really sets Buddhists apart from Enlightenment?  Getting attached and clinging to ideas rather the simplicity of a “very simple teaching” of Four Noble Truths?
Should we all study, for example Abhidharma? Buddha did not - he sat down for 49 days under a Bodhi tree, without reading anything of sorts. So, maybe abandoning reliance on sings and concepts yields greater benefit to us?
Is it safe to say that a frustration of imbalance between our ideal, imagined, conceptual realisation causes suffering due to unmet expectations of the actual current experience? Is it then correct that we best incrementally broaden knowledge slowly, in tandem with progressive experience, because such balance leads to better sanity?


user-1: In my humble opinion;
For a person who is not so stupid as to realise his tiny-puny EGO, these six nails of Tilopa will be enough to reach the promised land.
Bare minimum Buddhism


Don't recall    : Let go of what has passed  
Don't imagine   : Let go of what may come    
Don't think     : Let go of what is happening now    
Don't examine   : Don't try to figure anything out   
Don't control   : Don't try to make anything happen  
Rest            : Relax, right now, and rest



user254: The suttas are more than "Four Noble Truths, Eightfold Path" -- maybe they're still relatively simple, though, when compared to the Abhidhamma.

If the doctrine were only the first three noble truths, that would have been a good beginning.
You can't have the fourth noble truth without asking or explaining what the eightfold path is -- then the existence of eightfold path raises further questions -- like, "what is 'right view'?", or, "what method of meditation?"
I think the anatta doctrine is helpful (and so, may be worth teaching) but apparently it's difficult to explain or to understand. I'm not sure where it fits into the 4NT or N8P: "right view", perhaps.
A lot of further doctrine is consequent to teaching anatta:

Te doctrine of the 12 nidanas for example, in my opinion, exists to explain what the "self" even is, if it isn't "me" ... and maybe as a prescription towards ending craving and attachment (i.e. by guarding the senses) ... and some doctrine about "birth" and so on.
Similarly the doctrine of the 5 aggregates also, IMO, exists to explain what is or isn't the "self" ... and it introduces doctrine about impermanence (after which, dispassion, etc.).

I hadn't mentioned "virtue" yet -- but the suttas do, in some detail, at least a book's worth. Not to mention the vinaya.
Something else which pervades the suttas -- the notion of skillful versus unskillful, the fact that some things tend toward suffering and some things tend away. Maybe it's necessary, to begin to draw distinctions like that, in order to say anything specific or prescriptive at all, and not only truisms? Once you begin, though, to analyse reality into dualities, perhaps there's a lot to say.
Other topics in the suttas include:

Social interactions (friends and brahmaviharas)
Contradicting (or correction) of other (non-Buddhist) contemporary doctrines.
Success stories
Various lists -- fetters, hindrances, stages of enlightenment, factors of awakening
Answering FAQs -- "isn't desiring enlightenment a type of desire?" for example



Are the suttas enough or not?

Maybe not -- for example in the Noble search (MN 26) it says,

And so I was able to convince them. I would teach two monks while three went for alms, and we six lived off what the three brought back from their alms round. Then I would teach three monks while two went for alms, and we six lived off what the two brought back from their alms round. Then the group of five monks — thus exhorted, thus instructed by me — being subject themselves to birth, seeing the drawbacks of birth etc.

At least two of the suttas record for us what he told this first group of five monks, but (according to the quote above) there were more teachings that weren't recorded.
But maybe -- the Punna sutta for example tells of a monk who the Buddha instructed "with a brief instruction" and who then (successfully) went to practice alone.
According to that sutta, his "brief instruction" was dispassion towards sense objects (associating delight and attachment with dukkha)
I guess that "the Dhamma and the Discipline" were originally all there were -- except the Sangha as well -- I'm not sure why the Abhidhamma was developed too so I can't address that.


"What is the barrier and to what extent do we need to understand things by intellect?"

"Intellect" as opposed to what? Isn't dukkha and craving and so on maybe a statement about "emotions", and not just intellect? So emotions, at least, too.
And there's an extent to which mind conditions the body and vice versa, so that as well.
And society too; or seclusion.

But ... if you're studying Maths, for example -- which I guess is an example of an "intellectual" exercise -- I think you're not going to learn how to do Maths just by reading Maths lectures or watching videos.

You may need a live teacher for some reason
What about motivation, what's to motivate you?
You may have questions
You may benefit from a teacher's advice, correction, or example
You need some kind of practice or exercise, you need to practice applying what you learn (and learn to apply)


user43: My teacher said, this happens for two reasons:

students don't meditate and
students read books without talking to live Buddhist teachers (former students who got it) to get a sense of high-level meaning and practical real-life implications.

Because of this, students don't see how the teaching connects with real life.
Since they don't see how the teaching connects with real life -- all they have is theory (=a bunch of concepts).
Since all they have is a theory, they try to extract some knowledge by speculatively analyzing the available concepts.
Without connection to real life, the concepts can no longer be simple approximate pointers to the most important "gist" of what is really happening. Instead, the students are forced to try and keep the concepts precise - with all the details, exceptions, and endlessly recursive definitions.
This is how speculative analysis leads to further conceptual proliferation.
When students meditate and talk to live teachers, their theory connects with practice in real-life. Then the concepts can be simple (even if imprecise) pointers to what happens in real-life. These pointers do not need too much elaboration, exceptions, and definitions. Then Dharma is embodied in practice instead of proliferating as concepts.
Intellectual understanding is important. I don't agree that Enlightenment is something irrational, completely beyond the intellect. In my opinion, Enlightenment is attained through understanding. However, it has to be live, practical -- and not just theoretical -- understanding, that goes hand-in-hand with implementation.

user-1: The problem arises due to a misunderstanding of how Buddhism is supposed to be practiced. 
Especially in the West people tend to study the teachings in a greater degree than practicing it. The depth and profundity of Buddhism can never be understood by intellectual thinking alone. It will only lead to mental proliferation and more questions. Its an unending spiral.
A scientist will never understand reality if he only theorizes about it. It will only lead to more questions. He has to personally experience reality by performing experiments and thereby gaining feedback from reality, that can correct his (wrong) views/theories.
A person sitting in a restaurant reading the menu card will never understand the taste of the food unless he actually orders and eats it. Merely reading and thinking about the food will never result in a personal, emphirical experience of tasting.
Buddhism has to be practiced in order to personally experience the nature of reality. When practice deepens, a lot of the previous questions and doubts will subside.
There needs to be a balancing of the faculties, i.e. more Wisdom, gained from meditation practice.
TL:DR: Less thinking, more practicing!
