For a long time the religious world had been weakened and materialism had advanced; the spiritual forces of life were waning, moralities were becoming degraded, composure and peace had vanished from souls and satanic qualities were dominating hearts; strife and hatred overshadowed humanity, bloodshed and violence prevailed. God was neglected; the Sun of Reality seemed to have gone completely; deprivation of the bounties of heaven was a fact; and so the season of winter fell upon mankind.
But in the generosity of God a new springtime dawned, the lights of God shone forth, the effulgent Sun of Reality returned and became manifest, the realm of thoughts and kingdom of hearts became exhilarated, a new spirit of life breathed into the body of the world and continuous advancement became apparent.
