Is there a 30-day meditation course?

Courses in StillMind are measured in sessions rather than days, and they run between three and fourteen depending on the type and the length you choose. There is no timetable, so a course might take a fortnight or a couple of months and neither is wrong. If you want to practise daily for a month, you can take one session a day and keep practising once the arc completes, or build a second course when the first one ends. Counting sessions rather than days means a missed day never ends anything.
