All Buddhas have the same wisdom and ability. All Buddhas are in
a state of ONENESS (Yi4 Zhen1 Fa3 Jie4) and they share the same
Dharma body. But the vows made prior Buddhahood for all Buddhas
were different.
"Fo2 Guang1", "Zhong4 Shen1 Fo2 Yuan2" and "Zhong4 Shen1 Gen1 Ji1"
bu ping deng.
All Buddhas from all directions and all dimensions wish for all
sentient beings to chant Amitabha's Name and to be borned into Pure
Land.
Hence, if someone sincerely with one heart, chants the name of
Buddha Amitabha. All Buddhas will rejoice and bless this
person.
Na Mo A Mi Tuo Fo.
Hope this help.
