Whether various spells are really effective, please ask those who have personal experience.

I have experienced the efficacious effect of the ZHOU saying in the "Heart Sutra", which can be said to have directly cured serious stomach problems.

At that time, I had just come into contact with Buddhist scriptures and did not understand them at all. When I saw that the scriptures said "it is true and not false," I firmly believed that the Buddha would not lie, so I read it hard. A miracle happened, the stomach problem was cured without medicine.

But now, I have memorized the "Heart Sutra" and "understood" the meaning of the "Heart Sutra". When I encounter illness, I recite it again, but it doesn't work! So it depends on your fate. Whether it works or not depends on you.
