“In bed that night I invented a special drain that would be underneath every pillow in New York, and would connect to the reservoir. Whenever people cried themselves to sleep, the tears would all go to the same place, and in the morning the weatherman could report if the water level of the Reservoir of Tears had gone up or down, and you could know if New York is in heavy boots.”
― Jonathan Safran Foer, Extremely Loud & Incredibly Close

“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

“The Greek word for "return" is nostos. Algos means "suffering." So nostalgia is the suffering caused by an unappeased yearning to return.”
― Milan Kundera, Ignorance

“You are the only one who has understood even a whisper of me, and I will tell you that I am the only person who has understood even a whisper of you.”
