Tazkiyat al-nafs, purification of the soul

What it is: Tazkiyat al-nafs is the purification of the soul or self, a process of moral and spiritual discipline aimed at combating vanity, disordered attachment, and the illusions of the ego.

How the tradition understands it: Sufism often treats this work as a continuous journey of repentance, inner examination, self-control, and ethical refinement.

Textual basis and context: Qur'anic verses about those who purify the soul, along with works of asceticism and spiritual ethics, sustain this belief. Throughout history, it has become one of the most constant themes of Sufi literature.

Debates and variations: The techniques and classifications of the soul vary among masters and orders, but the general principle is very widespread.
