HaYom Yom 20 & 21 Tammuz

A very interesting contrast:

HaYom Yom is "Yeder Tog Iz Gelebt" with HaYom Yom every day comes alive! (Source?)

So on 20 Tammuz you 'get up' with there being 3 levels of contemplation (hisbonenus); during learning, before davening and during davening. And concludes that sometimes you may be able to have feelings for G-dliness without working on it but that's unusual. Generally speaking, when working on yourself, you need these 3 steps (ayin sham).

This seems to be a blueprint for a structure of how you work on yourself.

The next day on 21 Tammuz you 'get up' and discover that in exile, in golus, the structure is gone. The place (of the Beis Hamikdash) is still holy, your foundation is still intact but the building above the foundation is destroyed.

Weren't we working on the structure yesterday? To discover today it's gone?

Your comments would be greatly appreciated!
