The direct perception of ordinary beings is not reliable

From the perspective of ultimate meaning, all dharmas are, for the Buddha, direct perception/valid direct cognition, while for ordinary beings they are erroneous cognition/non-valid cognition, because the Buddha completely and truly knows things as they are, whereas sentient beings know them mistakenly. Since beginningless kalpas, the six consciousnesses of sentient beings have been deliberately or unintentionally deceiving their own manas, transmitting to the manas only erroneous cognition/non-valid cognition realms. As a result, the defilement of the manas has grown ever more severe, and ignorance has become ever deeper. If the mind consciousness, through contact with the correct authoritative teachings of the sages (āgama), through proper mental engagement (yoniśo-manaskāra) and correct deliberation, can then allow the six consciousnesses and the manas to have realms of direct perception that accord with the Dharma and with reason, they will thereby come to know the true facts of all dharmas. When ordinary beings observe all dharmas through direct perception/valid direct cognition, they believe it to be real, but in fact the results are all false and illusory. Ordinary beings have never reached a single correct conclusion; what they arrive at are almost always erroneous conclusions. The direct perception/valid direct cognition of ordinary beings is unreliable, because they lack the genuine wisdom of the Buddha's teachings. Relying on this so-called direct perception/valid direct cognition, they have, life after life, suffered the misery of birth-and-death in saṃsāra because of these erroneous conclusions.
