After locking the door, you may feel anxious about things like locking the door and the source of fire, so you may unlock the door and re-enter the house. You are feeling a great deal of satisfaction in your current life. You may be so satisfied as to feel a sense of dependency, saying, "I can't imagine losing my current life!" and "I won't be able to go on living!" Recognize the value of your current life again and continue to maintain it in the future!
