Sufism of Rumi, Hafez and Attar is rooted in Zoroastrian Mysticism, Syriac Christian Monasticism, Gnosticism, Hinduism, & Zen Buddhism.
Many Sufis have been persecuted and murdered by Muslims throughout Iranian history!
While Sufism is a spiritual path leading to divine love by practicing loving kindness towards others, Islam is an organized religion of dominations, discriminations, oppressions, unjust laws and brutal punishments.
