It is already the end of the third day. Hopefully, you will take advantage of the time remaining on this retreat and learn to isolate yourself. Now, while you have the opportunity, work hard. When you return to daily life, it will be impossible to isolate yourself from family, friends and the environment. Vexations will inevitably arise. However, if your practice is strong, you will be able to cut off these vexations before they become rooted in your mind.
