"_Blessed are the meek," "Blessed are they that hunger and thirst
after righteousness." "Blessed are the peacemakers_." It would not
be impossible to trace a relation between higher space thought and
the other beatitudes also, but it will suffice simply to note the
fact that the central and essential teaching of the Sermon on the
Mount, "Let your light shine before men" is implicit in the
conviction of every one who thinks on higher space: he must _live
openly_. By continual dwelling upon the predicament of the flat-man,
naked, as it were, to observation from an eye which looks down upon
his plane, we come to realize our own exposure. In that large world
all that we think, or do, or imagine, lies open, palpable; there is
no such thing as secrecy. Imbued with this idea, we begin to live
openly because we must; but soon we come to do so because we desire
it. In making toward one another our limited lives open and manifest,
we treat each other in the service of truth as though we were all
members of that higher world. We imitate, in our world, our true
existence in a higher world, and so help to establish heavenly
conditions upon earth.
