Daimoku is like light; as the Daishonin says, "a lantern lighting up a place that has been dark for a hundred, a thousand, or ten thousand years." Similarly, the moment we offer prayers based on daimoku, the darkness in our lives vanishes. This is the principle of the simultaneity of cause and effect. At that very instant, in the depths of our lives our prayer has been answered.
The inherent cause of a deep prayer simultaneously produces a latent effect. While it takes time for this effect to become manifest, in the depths of our lives our prayers are immediately realised. So at that moment light shines forth. The lotus (renge), in blooming and seeding at the same time, illustrates this principle of simultaneity of cause and effect.
Therefore it is important that we offer prayers with great confidence. The powers of the Buddha and the Law are activated in direct proportion to the strenght of our faith and practice. Strong faith is like a high voltage - it turns on a brilliant light in our lives.
Prayers are invisible, but if we pray steadfastly they will in time definitely effect clear results in our lives and surroundings.
