Remark: Baal HaSulam writes that joy is an indicator of good deeds. If good actions are not for your own sake, then joy and gladness are revealed.
Answer: Joy in spirituality is the result of the correct actions, while on the earthly level it can be the other way around—you steal and rejoice.
Question: What is a good action?
Answer: Good actions are actions that are similar to the Creator’s.
Question: What level of correction of each person will be sufficient for universal anxiety to be replaced by universal joy?
Answer: For anxiety to be replaced by joy, we need to find the feeling of the Creator.
The feeling of the Creator is called “faith.” That is what we need. Then all anxieties will turn into joy.
