Latifa, plural lataif, means a subtlety or a fine thing, and in Sufi psychology it names a centre of perception in the human being that is not the physical organ it is located at. The scheme usually meant by lataif-e-sitta, the six subtleties, is the one elaborated within the Naqshbandi order, where five of the centres are assigned to the alam al-amr, the world of command, and one, the nafs, to the alam al-khalq, the world of creation. That distinction carries weight inside the system, because it separates the centres held to belong to the divine command from the self that has to be worked on.
The five of the world of command are qalb, the heart, ruh, the spirit, sirr, the secret, khafi, the hidden, and akhfa, the most hidden. Their usual placement is on the chest, with qalb below the left breast and the others distributed across it, and the nafs at the brow. Ahmad Sirhindi, the seventeenth century Naqshbandi shaykh known in the tradition as Mujaddid Alf-i Thani, is the figure most associated with the elaboration of this arrangement, and the branch of the order that follows his formulation is called the Naqshbandi-Mujaddidi after him.
Correspondences beyond the names vary by lineage. Colours and prophetic associations are taught for the centres in a number of Naqshbandi branches, and the tables do not agree with one another closely enough to be set out here as a single fixed scheme.
