What is karmic taboo?

What is karmic taboo? Try it yourself and you'll know. For example, chanting Buddha and holding spells, practicing every day, and watching when you have time. Sometimes I feel dizzy, have a headache, worry and be agitated. Ignore it and keep practicing. After that, you will feel clear-headed and refreshed. The above situation is a karmic taboo. Karma always exists. If you don't practice, you may not be so fast. But once you practice hard, it will be found soon. But as long as you have the determination to pass this level, you will be broad.
