Nachman of Breslov,
Likutei Etzot
“ We must pray and plead a great deal with Hashem Yitbarakh to make us worthy of true lowliness and humility. We really have no conception what is true humility and lowliness, because being despised and worthless is certainly not the purpose; what people call a Shlemazelnik. For humility is the essence of the life that is in every single limb, and it's the bliss of the Coming World, and it's certainly not the aim of the Coming World to be despised and worthless etc., God forbid. ”
