“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

“Body cells replace themselves every month. Even at this very moment. Most everything you think you know about me is nothing more than memories.”
― Haruki Murakami, A Wild Sheep Chase

“No, our science is no illusion. But an illusion it would be to suppose that what science cannot give us we can get elsewhere.”
― Sigmund Freud, The Future of an Illusion

“Memories warm you up from the inside. But they also tear you apart.”
― Haruki Murakami, Kafka on the Shore
