In fact, the name of Buddha is a spell. Both the Buddha's name and spell can communicate with the energy of the universe. Although the names are different, they are essentially communicating with buddhas and bodhisattvas, and there is no difference.

On the other hand, many spells contain Buddhist names, but we just don't pay attention to them. You can see shurangama mantra, with many Buddhist names. As we all know, the Great Mercy Mantra is actually the name of the Bodhisattva, and there is no doubt about it. The Buddha's name in the spell is a spell. Isn't the Buddha name in the spell also a spell? The name Amitabha is found in many spells, and it is also a spell. Therefore, you are right to say that Amitabha is the name of Buddha, and it is also right to say that it is a spell. There is no difference.
