The Buddha then relates how, having taken food, he began to meditate and passed through four stages of contemplation, culminating in pure self-possession and equanimity, free alike from all feeling of pain or ease. Such meditation was nothing miraculous but supposed to be within the power of any trained ascetic. Then there arose before him a vision of his previous births, the hundreds of thousands of existences with all their details of name, family and caste through which he had passed. This was succeeded by a second and wider vision in which he saw the whole universe as a system of karma and reincarnation, composed of beings noble or mean, happy or unhappy, continually "passing away according to their deeds," leaving one form of existence and taking shape in another. Finally, he understood the nature of error[322] and of suffering, the cessation of suffering and the path that leads to the cessation of suffering. "In me thus set free the knowledge of freedom arose and I knew 'Rebirth has been destroyed, the higher life has been led; what had to be done has been done, I have no more to do with this world[323].' This third knowledge came to me in the last watch of the night: ignorance was destroyed, knowledge had arisen, darkness was destroyed, light had arisen, as I sat there earnest, strenuous, resolute[324]."
On attaining enlightenment he at first despaired of preaching the truth to others. He reflected that his doctrine was abstruse and that mankind are given over to their desires. How can such men understand the chain of cause and effect or teaching about Nirvana and the annihilation of desire? So he determined to remain quiet and not to preach. Then the deity Brahmâ Sahampati appeared before him and besought him to preach the Truth, pleading that some men could understand. The Buddha surveyed the world with his mind's eye and saw the different natures of mankind. "As in a pool of lotuses, blue, red or white, some lotuses born in the water, grown up in the water, do not rise above the water but thrive hidden under the water and other lotuses, blue, red or white, born in the water, grown up in the water, reach to the surface: and other lotuses, blue, red or white, born in the water, grown up in the water, stand up out of the water and the water does not touch them." Thus did he perceive the world to be and he said to Brahmâ "The doors of immortality are open. Let them that have ears to hear, show faith."
Then he began to wonder to whom he should first preach his doctrine, and he thought of his former teachers. But a spirit warned him that they had recently died. Then he thought of the five monks who had tended him during his austerities but left him when he ceased to fast. By his superhuman power of vision he perceived that they were living at Benares in the deer park, Isipatana. So, after remaining awhile at Uruvelâ he started to find them and on the way met a naked ascetic, in answer to whose enquiries he proclaimed himself as the Buddha; "I am the Holy One in this world, I am the highest teacher, I alone am the perfect supreme Buddha, I have gained calm and nirvana, I go to Benares to set moving the wheels of righteousness[325]. I will beat the drum of immortality in the darkness of this world." But the ascetic replied. "It may be so, friend," shook his head, took another road and went away, with the honour of being the first sceptic.
When the Buddha reached the deer park[326], a wood where ascetics were allowed to dwell and animals might not be killed, the five monks saw him coming and determined not to salute him since he had given up his exertions, and turned to a luxurious life. But as he drew near they were overawed and in spite of their resolution advanced to meet him, and brought water to wash his feet. While showing him this honour they called him Friend Gotama but he replied that it was not proper to address the Tathâgata[327] thus. He had become a Buddha and was ready to teach them the Truth but the monks demurred saying that if he had been unable to win enlightenment while practising austerities, he was not likely to have found it now that he was living a life of ease. But he overcame their doubts and proceeded to instruct them, apparently during some days, for we are told that they went out to beg alms.
Can this account be regarded as in any sense historical, as being not perhaps the Buddha's own words but the reminiscences of some one who had heard him describe the crisis of his life? Like so much of the Pitakas the narrative has an air of patchwork. Many striking passages, such as the descriptions of the raptures through which he passed, occur in other connections but the formulæ are ancient and their use here may be as early and legitimate as elsewhere. In its main outlines the account is simple, unpretentious and human. Gotama seeks to obtain enlightenment by self-mortification: finds that this is the wrong way: tries a more natural method and succeeds: debates whether he shall become a teacher and at first hesitates. These are not features which the average Indian hagiographer, anxious to prove his hero omnipotent and omniscient, would invent or emphasize. Towards the end of the narrative the language is more majestic and the compiler introduces several stanzas, but though it is hardly likely that Gotama would have used these stanzas in telling his own story, they may be ancient and in substance authentic. The supernatural intervention recorded is not really great. It amounts to this, that in mental crises the Buddha received warnings somewhat similar to those delivered by the dæmon of Socrates[328]. The appearance of Brahmâ Sahampati is related with more detail and largely in verse, which suggests that the compiler may have inserted some legend which he found ready to hand, but on the whole I am inclined to believe that in this narrative we have a tradition not separated from the Buddha by many generations and going back to those who had themselves heard him describe his wrestling to obtain the Truth and his victory.
Other versions of the enlightenment give other incidents which are not rendered less credible by their omission from the narrative quoted, for it is clearly an epitome put together for a special didactic purpose. But still the story as related at the beginning of the Mahâvagga of the Vinaya has a stronger smack of mythology than the passages quoted from the Sutta-Pitaka. In these last the Bodhi-tree[329] is mentioned only incidentally, which is natural, for it is a detail which would impress later piety rather than the Buddha himself. But there is no reason to be sceptical as to the part it has played in Buddhist history. Even if we had not been told that he sat under a tree, we might surmise that he did so, for to sit under a tree or in a cave was the only alternative for a homeless ascetic. The Mahâvagga states that after attaining Buddhahood he sat crosslegged at the foot of the tree for seven days uninterruptedly, enjoying the bliss of emancipation, and while there thought out the chain of causation which is only alluded to in the suttas quoted above. He also sat under three other trees, seven days under each. Heavy rain came on but Mucalinda, the king of the serpents, "came out of his abode and seven times encircled the body of the Lord with his windings and spread his great hood over the Lord's head." Here we are in the domain of mythology: this is not a vignette from the old religious life on the banks of the Nerañjara but a work of sacred art: the Holy Supreme Buddha sitting immovable and imperturbable in the midst of a storm sheltered by the folds of some pious monster that the artist's fancy has created.
The narrative quoted from the Majjhima-Nikâya does not mention that the Buddha during his struggle for enlightenment was assailed or tempted by Mâra, the personification of evil and of transitory pleasures but also of death. But that such an encounter—in some respects analogous to the temptation of Christ by the Devil—formed part of the old tradition is indicated by several passages in the Pitakas[330] and not merely by the later literature where it assumes a prominent and picturesque form. This struggle is psychologically probable enough but the origin of the story, which is exhaustively discussed in Windisch's Buddha und Mâra, seems to lie not so much in any account which the Buddha may have given of his mental struggles as in amplifications of old legends and in dramatizations of metaphors which he may have used about conquering death.
The Bodhi-tree is still shown at Bodh-Gaya. It stands on a low terrace behind the temple, the whole lying in a hollow, below the level of the surrounding modern buildings, and still attracts many pilgrims from all Buddhist lands
