“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

“Solitude is the playfield of Satan.”
― Vladimir Nabokov, Pale Fire

“I'm not very good at knowing what other people are thinking, but I do know that you can see tragedy, real tragedy, sitting just inside a person's gaze. You can almost always see where a person has been if you look hard enough.”
― Mo Hayder, The Devil of Nanking

“It is late now, I am a bit tired; the sky is irritated by stars. And I love you, I love you, I love you – and perhaps this is how the whole enormous world, shining all over, can be created – out of five vowels and three consonants.”
― Vladimir Nabokov, Letters to Vera
