Why can't I feel the will of the Buddha when I burn incense recently?

I'm afraid you are too dependent. I forgot that everyone can become a Buddha and Bodhisattva.

"Guanyin bodhisattva's spiritual divination is the only divination allowed by Yinzu, but don't rely too much on it. Ask everything and go your own way. If all the questions are answered by the Bodhisattva, this is the true Bodhisattva way. It is not accurate because the Bodhisattva doesn't want you to indulge in divination. ~ Master Chang Guanyin?

"Since the practice of Buddhism, Buddhists and Bodhisattvas have never spoken to you directly, and so have Buddhists all over the world. Special karma only accounts for a small proportion, but intangible blessing and protection are endless and will not be broken for a day. " ~ Master Chang Guanyin
