Baha'u'llah declares that just as lesser living things have times of sudden emergence into new and fuller life, so for mankind also a "critical stage, " a time of "rebirth, " is at hand. The modes of life which have persisted from the dawn of history up till now will be quickly, irrevocably, altered, and humanity enter a new phase of life as different from the old as the butterfly is different from the caterpillar.. "the world will become indeed as a rose garden and a paradise." (119:1)
