TOOTH EXTRACTION DURING THE ULLAMBANA FESTIVAL
Question: Is it alright to go for a tooth extraction one week before the Ullambana Festival? This is because my dental appointment is a few days prior to the festival.
Answer: There are a lot more foreign spirits during the Ullambana Festival. If it’s not urgent, it would be better to do it after the festival. If you are someone who performs recitation and offers Little Houses on a regular basis and there is no impending karmic pass, then it is not much of an issue.
However, if this period coincides with your 3, 6, 9 predestined calamities, or you are experiencing some physical discomfort or things are not going smoothly, and you are unable to offer a sufficient amount of Little Houses, you may want to consider having your tooth extracted after the festival.
