THE SUTRA RECITATION

 
The SGI-USA offers the following guidelines on how to perform sutra recitation both for personal practice and at SGI-USA activities. These guidelines should also serve as the standard for teaching new members.

Face the Gohonzon, ring the bell, and chant Nam-myoho-renge-kyo three times.

Recite the essential portions of the " Expedient Means " chapter (part A).

Ring the bell and recite the verse section of the " Life Span " chapter (part C).

Ring the bell as you begin chanting Nam-myoho-renge-kyo continuously (daimoku) for as long as you wish.

To end daimoku, ring the bell, then chant Nam-myoho-renge-kyo three times.

In the morning, offer all five silent prayers, each segment separated by chanting Nam-myoho-renge-kyo three times.

In the evening, offer the second, third and fifth silent prayers, each segment separated by chanting Nam-myoho-renge-kyo three times.

In both the morning and the evening, after the fifth silent prayer, ring the bell and chant Nam-myoho-renge-kyo three times to conclude.      Source: tonidunlap.com
