Re: Why Sufism didn’t flourish in west?
I think its about times. West too has gone through some phases of exhibiting cultural values that East exhibits today like joint family system and usual gatherings of people at street level etc. Now you can see westernized tradition in Pakistan as well.
For sufism, when West was following Christianity practically there must be some sort of sufism there. Instead, there are some parallels between Islamic sufism and Chritianity. Rahbaniat/ seclusion is a practice from Chritianity which is followed by sharia condemning sufis same way followed in Christianity. And religious sufis apporve temporal seclusion.
for another example, you could observe the similar attitude in sufis as Christianity says, whoever slaps you on your right cheek, turn the other to him also
where as this was updated in Islam as if someone slaps you, you have full right to take revenge.
