What sums up life today
during this miasma?

As a material, theoretical life-basis is found to be a misapprehension of existence, the spiritual and divine Principle of man dawns upon human thought, and leads it to “where the young child was,” — even to the birth of a new-old idea, to the spiritual sense of being and of what Life includes. Thus the whole earth will be transformed by Truth on its pinions of light, chasing away the darkness of error.

Science and Health by Mark Baker Eddy, page 191:8

For thou wilt light my candle: the Lord my God will enlighten my darkness.
For by thee I have run through a troop; and by my God have I leaped over a wall.

Psalms 18: 28, 29
