The concept of Shelter is very common in Baha'u'llah's writings. I did a search on the online texts and it came up hundreds of times.

I ask because a key existential concept is Heidegger's "throwness" (Geworfenheit), which I see as the absence of a shelter amidst chaos of environmental complexities that we can't account for and don't really understand. When he is talking about Shelter, it's as though Baha'u'llah is talking about uncovering a divine organization underlying the chaos.
