“When the season of spring appears in the arena of existence, the whole world is rejuvenated and finds new life. The soul-refreshing breeze is wafted from every direction; the soul-quickening bounty is everywhere; the cloud of mercy showers down its rain, and the sun shines upon everything. Day by day we perceive that the signs of vegetation are all about us.“

– ‘Abdu’l-Bahá, The Promulgation of Universal Peace
