“Da ma limaala mimcha: ayin roeh — Know what’s above you, an eye that looks at you" Avos).
You have to work on it. You have to spend time thinking about it: Hashem is looking at you. If you only learn it in a stony way, then it has no effect on life at all. All the great teachings that you take into your mind have to be translated into your nerves...You should feel it with your sensory perception. .. Serving Hashem is happiness. We have to gain that feeling. — Contending with the Yetzer Hara (#788)
