"יש בן חורין שרוחו רוח של עבד, ויש עבד שרוחו מלאה חירות; הנאמן לעצמיותו – בן חורין הוא, ומי שכל חייו הם רק במה שטוב ויפה בעיני אחרים – הוא עבד."
"There could be a freeman with the spirit of the slave, and there could be a slave with a spirit full of freedom; whoever is faithful to himself – he is a freeman, and whoever fills his life only with what is good and beautiful in the eyes of others – he is a slave."
-Rabbi Abraham Isaac Kook
"May God save me from fragmentation of the soul."
