“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

“It was November--the month of crimson sunsets, parting birds, deep, sad hymns of the sea, passionate wind-songs in the pines. Anne roamed through the pineland alleys in the park and, as she said, let that great sweeping wind blow the fogs out of her soul.”
― L. M. Montgomery, Anne of Green Gables

“Never regret thy fall,
O Icarus of the fearless flight
For the greatest tragedy of them all
Is never to feel the burning light.”
― Oscar Wilde

“To write is to forget. Literature is the most agreeable way of ignoring life. Music soothes, the visual arts exhilarates, the performing arts (such as acting and dance) entertain. Literature, however, retreats from life by turning in into slumber. The other arts make no such retreat— some because they use visible and hence vital formulas, others because they live from human life itself.
This isn't the case with literature. Literature simulates life. A novel is a story of what never was, a play is a novel without narration. A poem is the expression of ideas or feelings a language no one uses, because no one talks in verse.”
― Fernando Pessoa, The Book of Disquiet
