Prayer is not sending in an order and expecting it to be fulfilled. Prayer is attuning yourself to the life of the world, to love, the force that moves the sun and the moon and the stars.
Flowers have incredible power. Their fragile beauty and brief life can teach us to enjoy without attachment, to experience deeply while knowing full well the experience is temporary. It is the same with all life... On the spiritual path it is not the pleasure we want to renounce, it is the attachment to the pleasure. Life will have its joys and its sorrows; to live fully we must live from the source, without attachment to either pleasure or pain.
