But Amitabha is, after all, the Buddha of the western paradise. Both Amitabha Sutra and Infinite Life Sutra say that Amitabha died, or in layman's terms, Amitabha will bless you, and Guanyin Bodhisattva will bless you. But do you think it is enough to recite amitabha in an emergency? Of course you can.
What's the difference between Buddha and Bodhisattva? You should be a disciple of Buddha, and all Buddhas and Bodhisattvas will be treated equally. Remember that Guanyin Bodhisattva is responsive and has confidence in Guanyin Bodhisattva in times of crisis. Will the Bodhisattva still blame you?
According to your own karma, you are confident in that, so you can study it. Besides, you have nothing to do, and it's good to look at something else.
