Intuition in Buddhism

the modern definition of intuition is instinctive knowledge (without using the rational process), or impression, hunch, suspicion - quite far apart on the spectrum. The former indicates gnosis, while the latter implies strong belief. Regardless, here's a good quote from the discourse Kitagiri Sutta:

“Monks, I do not say that the attainment of gnosis is all at once. Rather, the attainment of gnosis is after gradual training, gradual action, gradual practice. And how is there the attainment of gnosis after gradual training, gradual action, gradual practice? There is the case where, when conviction has arisen, one visits (a teacher). Having visited, one grows close. Having grown close, one lends ear. Having lent ear, one hears the Dhamma. Having heard the Dhamma, one remembers it. Remembering, one penetrates the meaning of the teachings. Penetrating the meaning, one comes to an agreement through pondering the teachings. There being an agreement through pondering the teachings, desire arises. When desire has arisen, one is willing. When one is willing, one contemplates. Having contemplated, one makes an exertion. Having made an exertion, one realizes with the body the ultimate truth and, having penetrated it with discernment, sees it.

As I see it, Awareness consists of Conscious awareness and Unconscious awareness. Countless things are going on in our minds all the time that we are not conscious of, yet they can come to consciousness when needed. A visual model would be an Iceberg: most of it is below the waterline, like most of our sensing and cognition is not conscious to ourselves. (The 'unconscious' is conscious of itself and knows what it is doing. Animals, for example, have barely any 'consciousness', yet they function just fine.)

As people develop, they grow in consciousness, such that more and more of their awareness is known to their conscious mind, as if the Iceberg was to slowly rise from the water until it was mostly or entirely in the air. Realized people do this.

Intuition, then, is simply that your 'unconscious' (the bulk of your mind) is doing its job of sensing, filtering and assessing below decks and sometimes it sends an alert to your conscious mind, which you are free to ignore (at your peril). It is not infallible but it is the best thing we have for staying safe and happy, until we become more fully Realized. Make sense?

This is related to the idea of Recruiting, where as we develop, we can use larger and larger proportions of the mind / brain / consciousness / whatever and awareness deepens, widens and becomes more full and less about sequentially processing ideas. See the movie LUCY. There is a nice post about: Recruiting "points of view in the mind" out there.

A simple example: I was walking in the woods with someone when I suddenly stopped and stooped down to peer at a spider that was about 3 mm across (1/8 inch). My friend asked how on earth I had noticed it while walking on a sandy, rocky, leaf-strewn path without looking down, and that most people could not have seen the blessed thing even if they were looking right at it! (I am over 6 feet tall). I said, "it was moving and it caught my eye." Since I try not to step on things in my walks but I don't wish to spend all my thoughtpower on that, I have developed a "process" that looks for things throughout my visual range (spiderwebs?) and notifies me. You could call it Intuition as much as anything else.

What has this to do with Buddhism? "I have no idea" (from the movie LUCY). See my profile also.

Buddhism likes reason and origin, pratityasamutpadaPratītyasamutpāda which tells that nothing happens without a reason. I do not think any sutta contains the term intuition, what Buddhism is interested in is pratityasamutpada when arriving at conclusions. The scientific method also has reason, but is more rigid than pratityasamutpada. More open and more realistic framework of pratityasamutpada can discover more than what scientific method discovers. If your current scenario fits with this frame pratityasamutpada, you can agree with it.

Simply I agree with Ajahn Sumedho, even without reading the book, that is via intuition. First of all we have six senses, not five senses. We cannot forget the mind. People should agree with the mind, the correct mind. You are more successful when using the mind because you cover a wider range, you are using your all six senses. I think you should continue according to the book. Some sources tell the sixth sense is intuition, but I am not sure whether mind in Buddhism and intuition in psychology, both being the sixth sense in respective fields refer to the same. I have read a lot of psychological stuff; books, articles and quotes etc. And I have a fair knowledge in basic Buddhism also. From what I have read, in a psychological or cognitive sense, there is no clear definition or agreed upon definition on intuition. I have read so many bad things on intuition in an organizational behavior textbook while Albert Einstein, Immanuel Kant and other great men have praised intuition a lot. If you go to mbti classification, most of those so called great men are intuitive types.
I have not met intuition in a Buddhist source so far, but it is a good thing when backed up with some reasoning and experience of the individual. In a psychological sense, some men are gifted with intuition, they already know things, so they can read between lines, avoid choosing a tree over the forest and learn faster and move ahead faster. When you mediatate, when you read stuff, when you practice stuff, your intuition develops. You know more things and you have it in practice. Such a developed intuition can be believed and it should be chosen over a few ordinary tangible things we see at the moment, because intuition covers an wider range of experiences and knowledge. But yeah the people who don't have a developed intuition should not trust it, but when it is developed, should trust it. Intuition is not blind but very powerful when it is backed up with experience and knowledge which are mostly acquired via the other five senses. In fact, if you do not trust the intuition, you will stagnate. So move ahead reading and practicing the book. Hope you got some clarification.
