Pesukei DeZimra is Level 2 of the structure of Hashem's relationship to reality. Plugging into how Hashem sees things is the key to accessing our own inner machinery clearly. Learning how to navigate the structure of the tefillah tools at our disposal helps us not only unlock Hashem within ourselves, but also clarify how to think about failure, error and priorities.
