The rhythm of the day is set by various timers today. Such a glow in the dark wall clock with a round dial can also remind you of important prayer, thanks to the sacral pattern on the shield in the form of hands folded to prayers.
The difference between the Green Cross and the Red Cross. Green Cross is a symbol of nature and life. To represent life in a spiritual sense there is no more suitable colour than green. Generally today, a green cross has a secular meaning and the most common use is health care. In particular, the green cross represents First Aid.
The basic Celtic Cross is a symbol comprising a conventional cross with a ring around the intersection of the stem and the arms (as per the more elaborate example above). While these crosses are associated with all Celts, their origin is in Gaelic Ireland and they were probably introduced to Scotland, Wales and parts of England by Irish Christian missionaries.
