Because people are suffering from demons and going through demonic tribulations, they get headaches when listening to Buddhist music.
I have a similar experience. For ten years,
Since the age of 26, I have read more than a dozen Buddhist scriptures in vernacular, including the Surangama Sutra, the Avatamsaka Sutra, the Lotus Sutra, the Lankavatara Sutra, the Enlightenment Sutra, etc.
I just learned that Arhat has four fruits. There are fifty-two levels of Bodhisattva.
Arhats and Bodhisattvas must break through the confusion of view, confusion of thought, confusion of dust and confusion, and confusion of ignorance.
Become a Buddha by seeing your nature and see the Tao. Trouble, Obstacles, Thirty-seven Paths, Six Perfections, Four Noble Truths, etc.
I have some understanding of Arhat Bodhisattva.
So arouse respect. Stop scorning them.
At the age of 36, I broke this ginseng and broke the evil tribulation
Now I am 41 years old. I listen to Buddhist music, the Heart Sutra, the Shurangama Mantra and the Great Compassion Mantra, and I don’t feel like I have a splitting headache.
I think that when a person suffers a demonic calamity, he is a demon. As soon as he listens to Buddhist music and Buddhist mantras, he will subdue his inner demons. That's why I have a splitting headache.
