When you begin chanting Nam-myoho-chanting renge-kyo you have embarked on a process of human revolution, where you gradually expand your life, conquer negative and destructive tendencies, and ultimately make the state of Buddhahood your dominant life condition. It is a practical method for bringing out the highest level of life in each of us, so we can derive maximum meaning from our lives.
The object of change lies deep within the life of each individual who practices. Through this process you will establish your ultimate purpose in life and work towards the perfection of self. In this manner you will gradually unfold your full potential and will be able to use all of your strengths and abilities in whatever arena you choose. Chanting Nam-myoho-renge-kyo will enable you to shine in your own unique way as you overcome your weaknesses and unfold your abilities to become unshakably happy.
Human revolution in the life of first one individual then another will grow into the reformation of society and the world. As President Ikeda says, “A great inner revolution in just a single individual will help achieve a change in the destiny of an entire society and, further, will cause a change in the destiny of humankind.” Buddhism Day by Day, p. 214
