In Lectures On Attaining Buddhahood in This Lifetime, by Daisaku Ikeda, published in 2007 by Soka Gakkai, Malaysia, President Ikeda comments on this famous Gosho Passage:
If you wish to free yourself from the sufferings of birth and death you have endured since time you must awaken to the mystic truth which has always been inherent in all living being. This truth is Myoho-renge-kyo. Chanting Myoho-renge-kyo will therefore enable you to grasp the mystic truth within you. It is called the Mystic Law because it explains the mutually inclusive relationship of life and all phenomena. That is why this sutra is the wisdom of all Buddhas.
As stated in the Gosho passage:
Life at each moment permeates the universe and is revealed in all phenomena. One awakened to this truth himself embodies this relationship. However, even though you chant and believe in Myoho-renge-kyo, if you think the Law is outside yourself, you are embracing not the Mystic Law but some inferior teaching. Therefore, when you chant the Mystic Law and recite the Lotus Sutra, you must summon up deep conviction that Myoho-renge-kyo is your life itself.
You must never seek any of Shakyamuni’s teachings or the Buddhas and bodhisattvas of the universe outside yourself. Your mastery of the Buddhist teachings will not relieve you of mortal sufferings in the least unless you perceive the nature of your own life. If you seek enlightenment outside yourself, any discipline or good deed will be meaningless. For example, a poor man cannot earn a penny just by counting his neighbor’s wealth, even if he does so night and day. That is why Miao-lo states, “Unless one perceives the nature of his life, he cannot eradicate his evil karma.”
Rise to the challenges that life present to you, we can transform our karma and reveal our true potential.
