Useful, but chanting the spell will get auxiliary blessings.
However, if you don’t know how to recite mantras and want to get a better response, you can go to the temple to worship Buddha, ask for Buddhist blessings, and help you practice. Incense can convey information to the void Dharma Realm.
A medium that receives blessings from all directions should not be underestimated. Therefore, buying a good incense can be very helpful. If you are willing, I suggest you go to the Wuxiang Copper Stove and buy a few boxes of praying incense made from pure natural plants to pray to the Buddha.
You will be able to get blessings from the Buddha. Bless you; I have been using the pure natural plant incense from the Phaseless Copper Stove, which is still very good.
Amitabha!
