Mecma'u'l-bahreyn (the place where the two seas meet) is, by virtue of being the locus where necessity (wujūb) and possibility (imkān) flow together, the station of kāba qawsayn (the mystical station of 'the distance of two bow-lengths'). It is also said to be the station of the union of being (wujūd), in that it is the place where the divine names and the realities of creation are joined. (Kāshānī, 78; Jāmī, 96)
(See also: kāba qawsayn)
Mecma'u'l-cem (the place of the union), and the true annihilation (maḥq al-ḥaqīqī), is the annihilation of multiplicity (kathra) in unity (waḥda, i.e., oneness, singularity). (Jāmī, 96)
