Sincerity is having no doubts, no intermingling, and no interruptions.

When chanting “Amituofo,” it is to not doubt what Sakyamuni Buddha told us 3000 years ago or what Amitabha Buddha vowed in his 48 vows. It is having no doubt that we have the same nature as a Buddha and that we too can awaken. It is having no doubt when we are assured that our chanting is the cause and being reborn in the Pure Land is the consequence.

No intermingling is not chanting “Amituofo” one time and a mantra the next.

No interruptions is not allowing other thoughts to arise, including the thought, “I am chanting.”

The sincere mind is the mind dedicated to the aspiration to help others. It dwells in peace and joy.
