In the study of Buddhist philosophy, from the start one tries to transcend concepts, and one tries, perhaps in a very critical way, to find out what is. One has to develop a critical mind that will stimulate intelligence. If one cultivates intelligent, intuitive insight, then gradually real intuitive feeling develops, and any imaginary or hallucinatory element is clarified and eventually dies out. Finally, the vague feeling of discovery becomes very clear, so that almost no doubt remains. Even at this stage, it is possible that one may be unable to explain one's discovery verbally or write it down exactly on paper. In fact, if one tried to do so, it would be limiting one's scope and would be rather dangerous. Nevertheless, one finally attains direct knowledge, rather than achieving something which is separate from oneself. This can only be achieved through the practice of meditation, which is not a question of going into some inward depth, but of widening and expanding outward.
