Why have I broken off my relationship with Buddhism and no longer believe in Buddhism? Useless!

This situation shows that you have no relationship with Buddha in the first place. In other words, the relationship with Buddhism is too shallow.

People who have a connection with Buddha will benefit significantly from chanting sutras, chanting Buddha's name, and worshiping Buddha. You see, many people in Tibet go on pilgrimage, covering hundreds of miles and dozens of days to pray. This kind of respect and piety is by no means imposed by others, but the benefits of worshiping Buddha are endless, and the people themselves can understand it. There are also many vegans who have not eaten meat or fish for decades. This is not about endurance, but about enjoyment! People who have no chance to practice it don’t know that the benefits of Buddhism are actually very real.
