Let each one of God's loved ones centre his attention on
this: to be the Lord's mercy to man; to be the Lord's grace. Let him do some
good to every person whose path he crosseth, and be of some benefit to him. Let
him improve the character of each and all, and reorient the minds of men. In
this way, the light of divine guidance will shine forth, and the blessings of
God will cradle all mankind: for love is light, no matter in what abode it
dwelleth; and hate is darkness, no matter where it may make its nest. O friends
of God! That the hidden Mystery may stand revealed, and the secret essence of
all things may be disclosed, strive ye to banish that darkness for ever and
ever.
