The Non-atheist knows to say:
You, me, and everyone that ever existed or ever will in future are all each individual individuals.
Each soul is indivisable and pervades the entire body, it is indestructible,
No one is able to destroy that imperishable soul,
for the soul there is neither birth nor death at any time,
the soul has not come into being, does not come into being,
and will not come into being. the soul is unborn, eternal,
ever-existing and primeval, the soul is not die when the body dies,
the soul is indestructible, eternal, unborn and immutable
the soul can never be cut to pieces by any weapon,
nor burned by fire, nor moistened by water,
nor withered by the wind, the individual soul is unbreakable
and insoluble, and can be neither burned nor dried,
the soul is everlasting, unchangeable, immovable and
eternally the unchanged.
The temporal false-ego = the ego garnered via the particular birth. Such a temporal false-ego exists for the span of the life time. The body withers but the conscious life-force [the soul --atma, in sanskrit] continues to another birth ---thus lossing all of its Identity to the dust of time; and then to re-start another life-time . . . as per the Karma-phalam (fruits of actions/works) from the last lifetime. Scripture says that all facilities are accorded to all species without prejudice ---you get a future birth mechanically as per the stratum of cultivated sensibilities that "were remembered at the time of death".
Personal relationships, work skills, wealth, social status are all lost ---and the future birth is determined by the culmination of past works/the final thoughts at the time of death/life-long cultivated desires.
At death, unless one is informed of absolute truths (or that which approximate such absolute truths) one is destined fro repeated "relative" existence of striving to enjoy sans (without) ultimate purpose.
All past associations are lost upon a material body's death ---freeing it up to pursue any available future birth without overt effort ---as per the qualification of the souls level of cultivated sophistication.
