Hama-Oost
"All is He" — the pantheistic formula of unqualified monism.
Literally: "All is He"
The Persian watchword "hama oost," "all is He" — the popular summation of wahdat-ul-wujud, that nothing exists but God and all things are His manifestation. Iqbal contrasts it pointedly with "hama az oost" ("all is from Him"), which keeps creation distinct from the Creator. His own leanings, safeguarding the reality of the world and the self, run toward the latter, away from the all-dissolving identity that "hama oost" can imply.
Wahdat-ul-Wujood
The doctrine of the Unity of Being, that all existence is a single reality identical with God.
Wahdat
Oneness or unity, especially the singular reality of the Divine.
Hama-Az-Oost
"All is from Him" — the formula affirming that creation emanates from God while remaining distinct from Him.
Wahdat-ush-Shuhood
The doctrine of the Unity of Witnessing, that the unity perceived is one of consciousness, not of being, leaving God and creation distinct.
