"And it came to me then. That we were wonderful traveling companions but in the end no more than lonely lumps of metal in their own separate orbits. From far off they look like beautiful shooting stars, but in reality they're nothing more than prisons, where each of us is locked up alone, going nowhere. When the orbits of these two satellites of ours happened to cross paths, we could be together. Maybe even open our hearts to each other. But that was only for the briefest moment. In the next instant we'd be in absolute solitude. Until we burned up and became nothing."
— Haruki Murakami (Sputnik Sweetheart)

"Therefore, dear Sir, love your solitude and try to sing out with the pain it causes you. For those who are near you are far away... and this shows that the space around you is beginning to grow vast.... be happy about your growth, in which of course you can't take anyone with you, and be gentle with those who stay behind; be confident and calm in front of them and don't torment them with your doubts and don't frighten them with your faith or joy, which they wouldn't be able to comprehend. Seek out some simple and true feeling of what you have in common with them, which doesn't necessarily have to alter when you yourself change again and again; when you see them, love life in a form that is not your own and be indulgent toward those who are growing old, who are afraid of the aloneness that you trust.... and don't expect any understanding; but believe in a love that is being stored up for you like an inheritance, and have faith that in this love there is a strength and a blessing so large that you can travel as far as you wish without having to step outside it."
— Rainer Maria Rilke (Letters to a Young Poet)

"The only sadnesses that are dangerous and unhealthy are the ones that we carry around in public in order to drown them out with the noise; like diseases that are treated superficially and foolishly, they just withdraw and after a short interval break out again all the more terribly; and gather inside us and are life, are life that is unlived, rejected, lost, life that we can die of.
"
— Rainer Maria Rilke (Letters to a Young Poet)

"And you should not let yourself be confused in your solitude by the fact that there is something in you that wants to move out of it."
— Rainer Maria Rilke (Letters to a Young Poet)

"I believe that around us there is only one word on all sides, one immense word which reveals our solitude and extinguishes our radiance: Nothing! I believe that that word does not point to our insignificance or our unhappiness, but on the contrary to our fulfillment and our divinity, since everything is in ourselves."
— Henri Barbusse (Hell)

".... it is clear that we must trust what is difficult; everything alive trusts in it, everything in Nature grows and defends itself any way it can and is spontaneously itself, tries to be itself at all costs and against all opposition. We know little, but that we must trust in what is difficult is a certainty that will never abandon us; it is good to be solitary, for solitude is difficult; that something is difficult must be one more reason for us to do it."
— Rainer Maria Rilke (Letters to a Young Poet)
