Developing awareness of the intangible realities behind being is the purpose of the Torah's instructions. The distortions of the Etz HaDa'at led to a muting of those intangibles in our perceptual landscape. When repairing these distortions, using tools like Pesukei Dezimra, there are often competing elements present, and the halakha system relates to these competing elements with halakhot like the one in this episode.
