Geometry, norm, and exact and contemplated plot/form are considered as distinct features of Hafez's poems. The manipulation of these features will entail the loss of some grace. A part of these poems which can be improved is geometry and bihanbaz norm. That's the continuous attempts and deliberations made by Hafez to revise, manipulate and improve his own poems. The revisions and manipulations resulted in various versions and revised scripts all of which can be found in his Divan. Thus, those editing Hafez's Divan should necessarily recognize and include in the texts the versions derived from the revisions and manipulations on the basis of accepted norms.

In this article, first these developments will be presented by showing some revised scripts and versions. Then, an attempt will be made to delineate some of Hafez's manipulations in his poems for the purpose of accomplishing geometry of such exactness and contemplation.
