For Buddhists, all eight practices, except aggressive practice, should be as high as possible.

The role of spell cultivation is to increase your spell output and your seal success rate.

Although the Buddha does not rely on magic output, the high point is better than the low point.

This is only a minor point, and more importantly, spell cultivation provides an increase in the probability of successful sealing. Whether it is the Buddha's Vajrayana mantra or the six divisions in the wheel of karma, the success rate of sealing can be improved through spell cultivation.

So Buddhists also need magic practice.

I hope I can help you.
