Whenever I have been away from my daily meditation, I like to start with five minutes. It can be five minutes a day or several times a day. The goal is to do what works best for that day. Gradually I work myself up to more time as needed. Some people do not like meditation. Some feel it's idol time for the devil to wreck havoc in your mind. However, to that I would say, if your mind is never clear or calm, how can you ever hear God?
