[f18] This was very well understood by the Buddha himself when he first attained Enlightenment; he knew that what he realised in his enlightened state of mind could not be imparted to others, and that if it were imparted they could not understand it. This was the reason why he in the beginning of his religious career expressed the desire to enter into Nirvana without trying to revolve the Wheel of the Dharma. We read in one of the Sutras belonging to the Agama class of Buddhist literature, which is entitled _Sutra on the Cause and Effect in the Past and Present_ (fas. II.): “My original vows are fulfilled, the Dharma [or Truth] I have attained is too deep for the understanding. A Buddha alone is able to understand what is in the mind of another Buddha. In this age of the Five Taints (_pañca-kashāyā_), all beings are enveloped in greed, anger, folly, falsehood, arrogance, and flattery; they have few blessings and are stupid and have no understanding to comprehend the Dharma I have attained. Even if I make the Dharma-Wheel revolve, they would surely be confused and incapable of accepting it. They may on the contrary indulge in defamation, and, thereby falling into the evil paths, suffer all kinds of pain. It is best for me to remain quiet and enter into Nirvana.” In the _Sutra on the Story of the Discipline_, which is considered an earlier translation of the preceding text and was rendered into Chinese by an Indian Buddhist scholar, Ta-li and a Tibetan, Mang-siang, in A.D. 197, no reference is yet made to the Buddha’s resolution to keep silent about his Enlightenment, only that what he attained was all-knowledge which was beyond the understanding and could not be explained, as its height was unscalable and its depth unfathomable, containing the whole universe in it and yet penetrating into the unpenetrable”....
