How we cite our quotes:
Siddhartha was deeply shocked. So this was how things were with him, so doomed was he, so much he had lost his way and was forsaken by all knowledge, that he had been able to seek death, that this wish, this wish of a child, had been able to grow in him: to find rest by annihilating his body! What all agony of these recent times, all sobering realizations, all desperation had not brought about, this was brought on by this moment, when the Om entered his consciousness: he became aware of himself in his misery and in his error. Om! He spoke to himself: Om! and again he knew about Brahman, knew about the indestructibility of life, knew about all that is divine, which he had forgotten. (8.6)
Basically, Om! saves Siddhartha from suicide.
"It is good," he thought, "to get a taste of everything for oneself, which one needs to know. That lust for the world and riches do not belong to the good things, I have already learned as a child. I have known it for a long time, but I have experienced only now. And now I know it, don't just know it in my memory, but in my eyes, in my heart, in my stomach. Good for me, to know this!" (8.44)
Siddhartha distinguishes between what he knows intellectually to be true, and the profound sense of knowledge that permeates his entire spirit.
Now Siddhartha also got some idea of why he had fought this self in vain as a Brahman, as a penitent. Too much knowledge had held him back, too many holy verses, too many sacrificial rules, to much self-castigation, so much doing and striving for that goal! Full of arrogance, he had been, always the smartest, always working the most, always one step ahead of all others, always the knowing and spiritual one, always the priest or wise one. Into being a priest, into this arrogance, into this spirituality, his self had retreated, there it sat firmly and grew, while he thought he would kill it by fasting and penance. Now he saw it and saw that the secret voice had been right, that no teacher would ever have been able to bring about his salvation. Therefore, he had to go out into the world, lose himself to lust and power, to woman and money, had to become a merchant, a dice-gambler, a drinker, and a greedy person, until the priest and Samana in him was dead. Therefore, he had to continue bearing these ugly years, bearing the disgust, the teachings, the pointlessness of a dreary and wasted life up to the end, up to bitter despair, until Siddhartha the lustful, Siddhartha the greedy could also die. He had died, a new Siddhartha had woken up from the sleep. He would also grow old, he would also eventually have to die, mortal was Siddhartha, mortal was every physical form. But today he was young, was a child, the new Siddhartha, and was full of joy. (8.46)
Although spirituality is not a race to see who can learn the most scripture, nor an immersion in wealth and sex, Siddhartha had to go through both in order to be reborn.
