Sa (Mandaeism)
In Mandaeism, the ṣa () is a rolled-up piece of sacramental flatbread that contains nuts and raisins, is also used in ritual meals for the dead and has a phallic symbolism. It is rolled up like a scroll. It is distinct from the pihta and faṭira, which are flatbreads that are not rolled up. The ṣa is also mentioned as the 'great first sindirka (male date-palm)' in the Scroll of the Great Baptism (line 139 f.). See also
