Ahanu... it is not life that is to be escaped from... it is suffering, the duhkha, the misery and misfortunes of life, not life itself... this is what Buddha teaches...
There is an old western model of thinking that sees buddhism as something nihilistic, something fatalistic, something where there is no immortality and an end of all existence, but this belief was usually put about by christians who could not see that really, buddhism and chirtianity are not that different...
Buddha, like Jesus, came to assist people, not harm them...
the story goes...
Buddha was a posh prince, well off, cossetted, didn't suffer much. He knew he one day had to be a chief, and a warrior, but it was a long way off, and he spent his time enjoying himself. One day, he went out into the town, with a servant, to see some real life. While he was there, in the town, he saw... a crippled beggar, a really old man close to death, and a corpse...
seeing these things, he asked himself a few questions. He asked himself- what is suffering, and what can I do to end it? He asked himself- how can I stop old age, sickness and death?
He asked his servant about this- what can I do to stop this misery and misfortune of old age, sickness and death? and his servant told him...
Siddhartha, you silly ass. You can't stop old age and withering and decay and death. Even though you're young and handsome and rich, these things are coming your way too. There's nothing you can do about it. That's just the way it is...
Siddhartha then, was a wee bit scared. He didn't want to be old, and blind, and crippled. He didn't want to be a corpse, dragged onto a vehicle without much ceremony and dumped somewhere after a nice ceremony.
At that moment, he saw a sadhu, a holy man. He thought... ahhh.... maybe the holy man has the answer- I can escape sickness old age and death as a holyman!
Off he went to become an aranyaka, a forest dweller, a hermit in the woods, talking and thinking about God. He did what the others did- he got into Siva, and performed the rites of tapas, and tried to develop his yogi powers, thinking this would somehow grant him the immortality he wanted.
Unfortunately... that wasn't what he got. Yes, he became enlightened, sitting there under his tree, but he didn't find immortality. He found something else. He realised that honestly, everything withered, decayed, died, ended. Like believing in Jesus, believing in the Buddha won't make you immortal. Your body will die, like everything else. Instead, there was something else, something that went beyond description, something called sunyata... which, if you break it down, reads... the end of one's own giving to self...
this end of self is not extinction... this end of self is... expansion... gnosis... the real knowledge, the knowledge that there is something eternal, something much bigger than just you, something special...
there is... nirvana... not extinction, but the end of forests, the forest being a metaphor for delusion, a state where everything is clear, and real, and true...
In the meantime... people suffer... this was Buddha's message... like Jesus, Buddha wanted to end suffering, for people to be good to each other and enjoy life here, in our paradise...
as you eloquently put it, Ahanu...
"...As the Buddha began his mision, he concentrated on two important questions about existence: How can we minimize suffering--both our own and that of others? And how can we attain inner peace? The Buddha concluded that to live means inescapably to experience sorrow and dissatisfaction. But he analyzed the nature and causes of suffering much like a doctor would diagnose an illness--in order to understand and overcome them...
First the Buddha asks, "What are the symptoms of the world disease?" And his answer was, "Sorrow!" The First Noble Truth: "Suffering exists." Birth is attended with pain, decay is painful, disease is painful, death is painful. The Second Noble Truth: "It has a cause." The Buddha's next question was, "Can such a cure be achieved?" And his answer was, "Yes!" The Third Noble Truth: "It has an end." The Fourth Noble Truth: "There is a way to attain release from suffering." To reach nirvana, followers must follow the Buddha's prescribed remedy, which is the Noble Eightfold Path.
Therefore, "there is release from sorrow" cannot have meant "release from life" (life-renunciation, suicide, or anything of that sort), since that would hardly have been a return of the patient to health. Therefore, I have concluded that the Buddha's question's question was of release not from life, but from sorrow.
So, with Jesus, the Buddha can say, "I am come that they might have life, and that they might have it more abundantly."..."
As for staying in the forest...
the story I have heard says that Buddha didn't stay in the forest...
Buddha found some other pals in the forest, and told them about his great ideas, and they laughed at him, so he went home and told his family, and the servants, and his friends, and he got a little movement going. After that, he stayed in various deer parks and lodges of the elite and the nobles, and they helped pay for his campaigning as well as accomodated him...
sunyata is often translated as emptiness... but this is not what it is... nirvana is not peace, or the end, either...
you can remain thoughout ages that cannot be counted for the sake of a single creature's happiness and welfare, should you choose that...
but the quest is never about immortality- the quest is about something else entirely...
