Tariqas refer to spiritual paths or orders within Sufism, which is a mystical dimension of Islam. These groups focus on the inner, personal experience of God and often emphasize rituals, meditation, and the guidance of a spiritual master (sheikh) to achieve closeness to the divine. The development of tariqas played a significant role in the broader process of Islamization and the establishment of religious rule under Islam, as they helped to spread Islamic teachings and practices across diverse cultures.
