Bodhisattva rubbed incense ashes into a good word, and the fortune teller asked me to rub incense ashes into a good word by hand.

No This is not Buddhism, but superstition. Buddhists and Bodhisattvas are all accomplished people with great compassion and boundless magic. They help all sentient beings and show us how to get rid of life and death, transcend reincarnation and achieve positive results. They don't play tricks like incense ashes.

This phenomenon you are talking about is superstition, which is collectively called "looking at the head of incense", that is, judging whether it is good or bad according to the different forms of burning incense is actually not allowed. The length of burning incense is related to the quality, material, density, whether there is wind, oxygen distribution uniformity, ignition time, etc., but this does not mean anything, and the immortal will not enlighten you in such a low-level way (because since an ordinary person is dead, the strength of his soul can only hold a dream at most, but can't change the length of burning incense. Remember, faith is completely different from superstition and folk custom.
