that it does not numb you to the spirit that works within it.
Seek the spirit, but not out of spiritual lust or spiritual egoism;
seek it rather because you wish to become selfless in the practical life
of the material world.
Turn to the ancient principle:
"Spirit never without matter, matter never without spirit!"
And say to yourselves:
We will do everything material in the light of the spirit,
and we will seek the light of the spirit in such a way
that it enkindles warmth in us for our practical deeds.
