Sometimes, a person can only serve G-d with constricted consciousness.³⁸ – “smallness” (often referred as Mochin d'Katnus, “small-mindedness”) as opposed to Gadlus – “largeness” (or Mochin d'Gadlus, “expanded consciousness”). That is, he does not enter the Supernal Worlds at all, but merely thinks how the entire world is filled with His glory, and that He is close to him. Then he is like a child, whose mind has developed only a little bit. Nonetheless, though he serves G-d in smallness, he does so with great spiritual attachment. Tzava’as HaRivash, p. 7b
