One thing I found interesting about Saeed’s contemplation about prayer is that is was devoid about any mention of God. Most of the time when talking about prayer people will talk about their relationship with God. However, Saeed talks about his human relationships.
Of course, Saeed likely believes in God, but it seems that his primary reason for praying is the way it connects him to other people. For someone like Saeed who is not naturally inclined towards cutting ties immigration would likely be especially painful and destabilizing. It is understandable then why he began to pray more after immigrating. Prayer was what kept him tethered to his family and past. For Saeed prayer served as a portal to other times and people he had lost, just as the doors served as portals to other places.
