A singing bird in a cage attracts uncaged birds, and the sight of these uncaged birds will make the caged bird want to be free. LIkewise the chanting of Odaimoku will bring out the Buddha-nature within ourselves. The Buddha-nature of the gods Bonten and Taishaku will be called by the chanting and protect the chanter. The Buddha-nature of Buddhas and Bodhisattvas will be pleased to be called. For attaining Buddhahood quickly, one must lay down the banner of arrogance, cast away the club of prejudice and chant, “Namu Myoho Renge Kyo.”
Nichiren write this in his Treatise on Attaining Enlightenment through Faith in the Lotus Sūtra (Hokke Shoshin Jōbutsu Shō). While we whose faith is in the Lotus Sūtra are assured that we and all other beings will become Buddhas, we often wonder when that will happen. The Lotus Sūtra describes time in terms of uncountable kalpas, and each kalpa itself is an unimaginable amount of time. There is no shortage of time, or of lives into which we can be born to benefit other beings. But by practicing Namu Myoho Renge Kyo, we continue on our path to enlightenment, rather than being diverted into delusion.
