“Toska - noun /ˈtō-skə/ - Russian word roughly translated as sadness, melancholia, lugubriousness.

"No single word in English renders all the shades of toska. At its deepest and most painful, it is a sensation of great spiritual anguish, often without any specific cause. At less morbid levels it is a dull ache of the soul, a longing with nothing to long for, a sick pining, a vague restlessness, mental throes, yearning. In particular cases it may be the desire for somebody of something specific, nostalgia, love-sickness. At the lowest level it grades into ennui, boredom.”
― Vladimir Nabokov

“I think you travel to search and you come back home to find yourself there.”

“And a woman spoke, saying, "Tell us of Pain."
And he said: Your pain is the breaking of the shell that encloses your understanding.
Even as the stone of the fruit must break, that its heart may stand in the sun, so must you know pain.
And could you keep your heart in wonder at the daily miracles of your life, your pain would not seem less wondrous than your joy;
And you would accept the seasons of your heart, even as you have always accepted the seasons that pass over your fields.
And you would watch with serenity through the winters of your grief.
Much of your pain is self-chosen.
It is the bitter potion by which the physician within you heals your sick self.
Therefore trust the physician, and drink his remedy in silence and tranquillity:
For his hand, though heavy and hard, is guided by the tender hand of the Unseen,
And the cup he brings, though it burn your lips, has been fashioned of the clay which the
Potter has moistened with His own sacred tears.”
― Kahlil Gibran, The Prophet

“[...]the only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn like fabulous yellow roman candles exploding like spiders across the stars and in the middle you see the blue centerlight pop and everybody goes “Awww!”
― Jack Kerouac, On the Road
