What Are Direct Perception, Inference, and Mistaken Perception (Non-Valid Cognition)?

Direct perception (pratyakṣa) means being able to observe and contemplate a dharma directly in its presence, seeing its true appearance and confirming its current state, without distorting the true reality. If one cannot see the dharma's present state as it truly is, and cannot observe its true appearance as it really is, one will resort to other methods, such as comparing and contrasting against a reference object. This is inference (anumāna); it may yield a correct result, or it may not. For inference to be correct, there is a prerequisite: the dharma used as the reference object must be accurate and error-free. Then the accuracy of the comparison result will be somewhat higher. Because a ready-made reference object exists, no overly detailed deliberation is needed; not much wisdom is required, nor deep meditative concentration—dhyāna is not even necessary—and a result can be produced, though whether it is accurate is uncertain.

If one's wisdom of direct perception is insufficient, another method can be adopted: imagination, fantasy, and conjecture. One may follow a certain line of thought or track, or one may indulge in wild flights of fancy entirely without order or logic. This is erroneous cognition (non-valid cognition). Erroneous cognition is thinking without any evidence; the element of groundless imagination is considerable. Only when one lacks the ability to gather and grasp evidence is one forced to proceed this way. It is evident that erroneous cognition requires even shallower wisdom and no dhyāna at all. From this we can see that direct perception requires considerable meditative concentration and wisdom; its wisdom is extremely precious and trustworthy. The realization of the Buddha's Dharma relies precisely on the wisdom of direct perception.

In erroneous cognition, because there is no evidence, everything depends on the mind consciousness's imagination—like a kite in the sky, perhaps tethered by a string, perhaps not. In this process, the manas cannot exert any force; the manas's wisdom cannot soar through the sky like the mind consciousness, cannot imagine or conjecture. Whatever the mind consciousness thinks is simply taken as such, and the manas cannot confirm it; therefore realization is impossible—though coincidences and strokes of luck cannot be ruled out. In this way, the manas's wisdom does not grow; only the mind consciousness's wisdom grows. When encountering a dissimilar problem later, unable to draw inferences from one instance to others, the mind consciousness must engage in erroneous cognition all over again—showing that its growth in wisdom is very limited.

In inference, when two matters or principles are compared, it relies mainly on the mind consciousness's deductive and comparative function; the manas's wisdom cannot exert much force, and the manas can only watch from the sidelines. The manas cannot truly confirm the result, though correct results from inference cannot be ruled out. But it cannot resolve the manas's inner doubt; the manas's wisdom does not grow—only the mind consciousness's wisdom grows.

For example, take a towering tree whose height one wishes to determine. There are three channels: direct observation, inference, and erroneous cognition. The method of erroneous cognition is thinking, imagining, and guessing without any basis—having no experience with the tree's height, not knowing how to compare, and even less knowing how to observe it as it truly is. The result is predictable: one probably cannot even convince oneself, let alone others. The method of inference is to compare it with the utility pole nearby, with tall buildings, with the mountainside, and then arrive at an approximate value. The result is a state of mind that is half-affirming and half-doubting; outwardly one may appear more confident, but if someone insists on pressing the point, or if more conclusive evidence comes to refute it, one loses all inner assurance. Of course, if someone agrees with this result, one's confidence increases somewhat.

Beyond these, there is another channel and method: direct observation. But this is extremely difficult. It requires a great deal of evidentiary data, rich experience, keen and accurate observational power, meticulous thinking, and precise data. To have rich experience and a large body of accurate, error-free data requires arduous effort and a considerable period of exploration. The hardship is beyond what ordinary people can imagine; the meditative concentration during observation is beyond ordinary people; and the resulting wisdom is likewise beyond ordinary people.

Throughout the process of exploring and gathering data, the manas has been watching all along, gradually being influenced and permeated. Once the mind consciousness reaches a conclusion that is highly convincing, and the manas deliberates on it further, it will confirm it, because there are sound reasons and solid evidence. Since the manas lacks analytical ability due to its shallow wisdom, it believes what has ample evidence; it believes the realm of direct perception. In fact, this conclusion is also one the manas reaches itself: all the data is laid out there, very concrete, and the manas will naturally begin to deliberate and arrive at a conclusion. Only a conclusion one reaches oneself can be believed without doubt. Naturally, what one reaches oneself is what one trusts and accepts most; no matter what others say, one can resolutely take responsibility for it, with no room for negotiation, and it is not easily retracted.

Because direct observation is so arduous and difficult, those who seek short-term results and fear hardship are unwilling to explore painstakingly over the long term; those who have practiced for only a short time lack both meditative concentration and wisdom, and cannot accumulate sufficient experience; therefore they cannot accord with direct observation. Hence many people prefer inference and erroneous cognition, preferring conjecture and comparison, because these methods are relatively effortless, do not take much time, and require little power of concentration or wisdom to produce a final result. How easy that is! Such people want only the result, without the process in between.

Yet precisely this process in between is extremely important. It is the process of refining evidence, the process of permeating and influencing the manas, the process of subduing all kinds of afflicted states of mind, the process of quantitative change leading to qualitative change. Without this process, there is no qualitative change, and the afflictions of one's own mind can never be subdued or transformed. So there are some people who go around fishing for results, attempting to obtain the fruit easily without going through the painstaking process of investigation. Such a fruit is not one's own and cannot be enjoyed; one remains a pauper. To falsely proclaim oneself a Dharma King can only invite destruction—the consequences are dreadful.

At this point, some may ask: after all this talk, you still have not made clear what direct observation actually is. But let me tell you: the direct observation described by others, once you have learned of it, becomes inference—it is no longer direct perception. True direct perception requires you to observe and verify it yourself. Therefore, results obtained by fishing around, results obtained by guessing, are extremely unreliable. Even results fished out from someone who observed directly do not belong to you; and if the results are fished out from someone who reached them by inference, they belong to you even less and are even less reliable. To further spread and fish for results in this chain is truly dreadful. Here I solemnly warn those unwilling to put in hard work: only by personally investigating can one personally attain the fruit and freely use the fruit; otherwise it is a bitter fruit—a bitter fruit that one must fully and solely experience oneself. Karmic retribution is never false.
