“In the depth of winter I finally learned that there within me lay an invincible summer.”
Albert Camus
“In the depths of winter I finally learned there was in me an invincible summer”
“He who shall practice these twenty virtues shall become invincible in all his undertakings.”
Chanakya
“X in our alphabet being a needless letter has an added invincibility to the attacks of the spelling reformers, and like them, will doubtless last as long as the language. X is the sacred symbol of ten dollars, and in such words as Xmas, Xn, etc., stands for Christ, not, as is popular supposed, because it represents a cross, but because the corresponding letter in the Greek alphabet is the initial of his name --_Xristos_. If it represented a cross it would stand for St. Andrew, who "testified" upon one of that shape. In the algebra of psychology x stands for Woman's mind. Words beginning with X are Grecian and will not be defined in this standard English dictionary.”
Ambrose Bierce
“[His characters] are always 7 feet tall and invincible, mine are 5 feet 8 and nervous.”
Elmer Kelton
“I felt invincible. My strength was that of a giant. God was certainly standing by me. I smashed five saloons with rocks before I ever took a hatchet.”
Carry Nation
“The cross is the invincible sanctuary of the humble.”
Eli Cass
