Assalamu Alaikum, greetings

I don't think that question could be answered.
Everyone lives for a different reasons and one could be more than one of those answers.
Besides that, each word has more than one meaning, its each individuals interpretation that will depend on what they choose...
reminds me of qiyama when everyone will be saying "nefsi nefsi!" (myself, myself) and the rasul (pbuh) will say "ummati ummati!" (my ummah, my ummah)
fi aman Allah
w'salaam
