June 6

As in the physical world there are four seasons, so in the realm of religion there is the season of heavenly and spiritual springtime. When its outpourings gradually diminish, the trees of existence cease to be verdant and creeping torpor spreads, it will become like winter. The souls will become withered and distressed and the soil of the hearts will become full of thorns and thistles. There will be no flowers, no hyacinths, no greenery, no pleasure, no freshness and no cheer. Then, once again, the divine spring will raise its tabernacle. The gardens of the world of humanity will become green and verdant, full of freshness and purity. The flowers of reality will open and the trees of existence will bring forth enduring fruit. This is the law of God and is in accord with the world of creation and this is the cause for the reappearance of holy Manifestations Who effect renewal and change in religious laws and commandments.
