Dear Avira,
I don’t think kedusha means mere separation. It is a negation of the need/want. People mistakenly think that if you want it at all then it must be from a lack of kedusha, but real kedusha requires a negation of both. Sometimes the desire for it. And sometimes the fulfillment. Otherwise, it’s just a game to build up the appetite.
Part of it is definitely to tech myself not to notice it. If I would take notice of everything as a way of potential sin, and then struggle to overcome it, I would be both fully insane and a complete sinner.
Though partially insane and an incomplete sinner sounds like something I’m still striving for.
