Pressures in life, doubts about our Tafkid, or a in cooling our Bitachon, are all experiences that can potentially weaken our commitment to our Tafkid.
Sadly, there are times when our resolve is weakened, and the layer of Kabolas Ol starts to peel. The Yetzer Hara exploits and exaggerates the impact of these cracks, with the intention of washing away more and more of our layer of Kabolas Ol, R"L.
"Kabolas Ol is just a layer!" The Yetzer Hara argues. "It is not the real you. Wouldn't it be better if it was completely washed away so the true you can shine?"
Yes and no.
