Although most of the concepts the Buddha taught can be deduced logically, some are difficult to discover without profound insight like the Buddha’s. When Buddha Sakyamuni was propagating the Dharma, he also said it is difficult for an ordinary person to observe and understand cause and effect. Thus, before we reach a certain level of wisdom, it is best not to inspect the workings of cause and effect. Even if we try, we will not be able to come to any conclusion; we might even raise doubt over its validity.
