Why is it said that "forgetting bodhicitta and practicing Buddhism is a famous magic industry"?

Bodhicitta is the heart of becoming a Buddha. Our aim is to "seek Buddhism and Taoism on the top and turn all beings on the bottom" to achieve supreme bodhi. If all actions are not based on bodhi, then even if you practice good Buddhism, it is easy to create karma while blessing. Isn't this the cause of magic? Can't fundamentally solve the problem. Therefore, it is very important for practitioners to always remember bodhicitta.
