he must have grasped something much deeper than mere dialectics. There must have been something most fundamental and ultimate which at once set all his doubts at rest, not only intellectual doubts but spiritual anguish. Indeed, forty-nine years of his active life after Enlightenment were commentaries on it, and yet they did not exhaust its content; nor did all the later speculations of Nāgārjuna, Aśvaghosha, and Vasubandhu, and Asanga explain it away. In the _Laṅkāvatāra_ therefore the author makes the Buddha confess that since his Enlightenment, till his passing into Nirvana he uttered not a word.[f32] Therefore, again with all his memory and learning, Ānanda could not sound the bottom of the Buddha’s wisdom, while the latter was still alive. According to tradition, Ānanda’s attainment to Arhatship took place at the time of the First Convocation in which he was not allowed to take part in spite of his twenty-five years’ attendance upon the Buddha. Grieving over the fact, he spent the whole night perambulating in an open square, and when he was about to lay himself down on a couch all exhausted, he all of a sudden came to realise the truth of Buddhism, which with all his knowledge and understanding had escaped him all those years. What does this mean? Arhatship is evidently not a matter of scholarship; it is something realised in the twinkling of an eye after a long arduous application to the matter. The preparatory course may occupy a long stretch of time, but the crisis breaks out at a point instantaneously, and one is an Arhat, or a Bodhisattva, or even a Buddha. The content of Enlightenment must be quite simple in nature and yet tremendous in effect. That is to say, intellectually, it must transcend all the complications involved in an epistemological exposition of it; and psychologically, it must be the reconstruction of one’s entire personality. Such a fundamental fact naturally evades description, and can be grasped only by an act of intuition and through personal experience. It is really the Dharma in its highest sense. If by “the stirring of one thought” Ignorance came into our life, the awakening of another thought must put a stop to Ignorance and bring about Enlightenment.[f33] And in this there is no thought to be an object of logical consciousness or empirical reasoning; for in Enlightenment thinker and thinking and thought are merged in the one act of seeing into the very being of Self. No further explanation of the Dharma is possible, hence an appeal to _via negativa_. And this has reached its climax in the Śūnyatā philosophy of Nāgārjuna, which is based upon the teaching of the Prajñāpāramitā literature of Buddhism.
