(Greek, Νέμεσις) Literally "distribution" (of what is due), related to νέμειν [némein], meaning "to give what is due, distribute, allot, apportion one's due," from root *nem- "to divide, distribute, allot, to take." Nemesis is the law that balances nature, also called cause and effect, karma, which is managed by divine, awakened beings who balance the scales of Justice and Mercy. In Greek mythology, their work and intelligence was personified in the form of the goddess Nemesis, also called Adrasteia ("the Inescapable").
"Hymn to Nemesis. Thee, Nemesis, I call, almighty queen, by whom the deeds of mortal life are seen: eternal, much revered, of boundless sight, alone rejoicing in the just and right: changing the counsels of the human breast for ever various, rolling without rest. To every mortal is thy influence known, and men beneath thy righteous bondage groan; for every thought within the mind concealed is to thy sight perspicuously revealed. The soul unwilling reason to obey, by lawless passion ruled, thine eyes survey. All to see, hear, and rule, O power divine, whose nature equity contains, is thine. Come, blessed, holy Goddess, hear my prayer, and make thy mystics' life thy constant care: give aid benignant in the needful hour, and strength abundant to the reasoning power; and far avert the dire, unfriendly race of counsels impious, arrogant, and base." - Orphic Hymn 61 to Nemesis (C3rd B.C. to 2nd A.D.)
