We do not need to differentiate one from the other. Dwelling in a house is not only a functional issue, but also a spiritual one. The house is the locus of heart (kokoro), and the heart is the locus of god. Dwelling in a house is a search for the heart (kokoro) as the locus of god, just as one goes to church to search for god. An important role of the church is to enhance this sense of the spiritual. In a spiritual place, people find peace in their heart (kokoro), as in their homeland.
