Haji Baktash Veli, a murid of the Malāmatī-Qalāndārī Sheikh Qutb ad-Dīn Haydar, introduced Ahmad Yasawi's doctrine of "Four Doors and Forty Standing" into his order.
A tariqa is a religious order of Sufism, or specifically a concept for the mystical teaching and spiritual practices of such an order with the aim of seeking haqiqa, which translates as "ultimate truth".
"Tariqat" in the Four Spiritual Stations: The Four Stations are Sharia, Ṭarīqah, Haqiqa, and the fourth station marifa, which is considered "unseen" and actually located at the center of the haqiqa region. It is the essence of all four stations.
