My Response: In this case, Bina is like air. We must understand that these are allegories. Many peoples still live in various caves or shelters, but this does not give them anything extra.
What is meant here is that a person consciously chooses such a state, such a model of behavior, that would raise him above egoism called earth so he would acquire the quality of altruism, the quality of bestowal, the quality of connection with others, called Bina.
A person creates such qualities in himself through his own efforts. He attracts the quality of light, of the upper world, the quality of bestowal. This, in general, is the power of the Creator, the power of Bina, with which one organizes something like a shelter in himself. Although one cannot fully ascend and move to a higher level in the spiritual world, at least in his state he creates a bubble for himself filled with a higher quality and exists in it.
