It is also selfish and altruistic to recite "There is no Amitabha Buddha in the south" sincerely and then put incense ashes in the big incense burner of the temple to continue to offer sacrifices to the Buddha and accumulate virtue. In addition, incense ashes can also be buried in clean soil. As the saying goes, "dust to dust, soil to soil". Burying them underground to support the prosperity and growth of all things is also planting good karma for yourself, and there will be good results in the future.
Of course, you can also choose to sprinkle incense ashes in running water and let them drift with the flow. Anyway, our hearts must be clean. People who understand Buddhism know very well that learning Buddhism cannot be persistent, but must be accompanied by good karma. Insist on doing anything, there will be a sense of separation, there will be right and wrong, and troubles will follow. This is not our original intention of learning Buddhism, nor is it the result we want.
