Is it better to chant Buddhist scripture or Buddha?

Chanting scriptures, holding spells and chanting Buddha are all excellent.

All of the above will have great merits. As for which scripture to read and what spell to hold, it depends on karma. What kind of sutra do you like or which spell is convenient to hold, and which one corresponds to you, just do it.

Chanting Buddha, the holy name of Amitabha, induces ten Buddhas. I often think of it, and over time, I will understand the mystery.
