April 15

One of the generating powers of this spiritual springtime is tempestuous and soul-stirring in nature; causing lightning and thunder, high winds, torrential rain, and roaring floods. These in turn cause the orchards and fields to become verdant and fruitful. The other is the inherent capacity for growth latent in the blessed seed. It is this capacity that causes the seed to grow as an essential necessity. The rays of the Sun of Truth and the sprinklings of the cloud of bounty help it to grow and become a mighty and fruit-bearing tree, providing a celestial retreat for the guided birds of the field. The overall divine design which leads humanity to spiritual maturity is not within our control; it is well guarded in God’s hidden treasure house and its realization is dependent on His Will.
