The real power of our calendars comes when you subscribe to them and they appear on your desktop and/or mobile device calendars. They help you keep meditation in mind. It's the beginning of being mindful.
Most people look at their mobile phone dozens of times a day. Something that's natural to check is your calendar. If you're trying to become a meditator, in the beginning, it's good to have help reminding yourself you are now a meditator.
By adding either our daily or weekly calendar to your calendar world, you are more likely to remind yourself of your desire to become a regular meditator. This is a good help to move you from being a person who likes the idea of meditation, to being a person that meditates.
