The word meridian comes from the Latin ‘meridies’, meaning “midday”; the subsolar point passes through a given meridian at solar noon, midway between the times of sunrise and sunset on that meridian. (wikipedia)
This cycle continues, day in and day out… ad infinitum; much like one’s journey in Brazilian Jiu-Jitsu. There are markers along the way, much like hours on a clock or days on a calendar and sometimes we pause and acknowledge the time’s passing. No matter what, everything continues to move forward.
