When Nichiren Buddhists pray, they are making themselves more mindful of the effects they wish to see in their lives, and raising their life-state in order to enable them to create the causes to achieve those effects.
It is important to remember that our prayers reflect our life state. In that respect, prayer is a solemn means to raise our life-state or condition. To receive exactly the results for which we are praying, it is crucial to make a determined, single minded effort toward that goal.
This is the true path of manifesting faith in our daily life. Those of us who proceed along this narrow path, day after day, month after month, year after year, will develop, without fail. Just as a sapling grows into a mighty tree, to become a person of outstanding strength and character, one with wisdom, courage and compassion, relies on us remaining true to our chosen path.
