Atonement
The Hebrew word for atonement is kaphar (kaw-far). Its definition, “cover, expiate”; #3722
Of course it would be after a unilateral (Yahweh being the lone, sole enforcer) covenant that the idea of mental atonement would be revealed. Our first glance would come at

Exodus 29:33 — “they (souls ruled by and for Yahweh; Israyl) are to eat (consciously consume) these things (mental substance) with which the atonement (mental covering) was made, to consecrate (consciously hedge in and guide) and to sanctify (consciously set apart) them [mind judges/priests]; but a stranger (thought foreign to the will of Yahweh) shall not eat (mentally consume), because they [consecrated, sanctified, atoned for thoughts] are holy (consciously pure).”

A thorough review of Leviticus chapter 16 is both necessary and warranted, as well as a brief overview of some specific verses in Numbers chapter 29.

Leviticus 16:1 — And Yahweh spoke (consciously resounded) to Ceo Mosheh (thoughts that “draw out” Yahweh’s will) after the death (absence in consciousness) of the two (two is “division”) sons (mental “builders”) of Aaron (thoughts that are “illuminated” yet not fully cognizant of absolute truth), when they [NaJolab — “impulsion, spontaneous”; impetuousness / Abihu — “father is”; belief in oneself], offered (consciously “apportioned”) unauthorized fire (mental judgment) before Yahweh and died (removed from thoughts).

Division, impetuousness and self reliance within one’s mind leads to bad judgment and false perceptions of Yahweh’s will, and the soul (mind) being perfected must go through this process; the “death” of such thoughts within.

v.2 — And Yahweh said to Mosheh, ‘Tell your brother (mental “affinity”, co -faculties in thought) Aaron (yet fully formed enlightenment within) not to come whenever he chooses into the Most Holy Place (the “sacred” place in the minds of chosen souls where the Temple (conscious “capacity”) of Yahweh dwells; the front seat of the brain), behind the veil (“spreading, tread”; separation place in the mind; Yahweh’s will and the carnal will) — in front of the mercy (“lid, cover”; protection in thoughts for chosen souls) seat (thoughts “reserved” for Yahweh’s glory), on the ark (“box”; thoughts gathered together according to Yahweh’s will alone), otherwise he [limited enlightenment] will die because I (the Perfect Conscience) appear in the cloud (“covert, cover”; mental mysteries yet perceived) over (protecting) the mercy seat.

The warning is clear. Each chosen soul must internally recognize the admonishment to not be so quick to believe that o,
“Every thought you think”, meets the standard of perfection produced by the will of Yahweh alone. To act upon each thought as if it “Must be the will of Yahweh”, is a fool’s errand. In order to attain to (understand) the will of Yahweh one must recognize all mind patterns, as per the mind “Laws” expressed with Hebraic words and their specific intent, or one will fall at the entrance into His Most Holy Place. The mental “veil” will remain.
