They do this in many ways. They ward off evil spirits. Finally, the guards offer friendship and welcome to well-meaning visitors. In Korean folk tradition and literature, these guards are satirical in appearance and function. It is believed that energy, both physical and spiritual, comes from the mountains.
Temple buildings allow fresh air to pass through so the energy is always present within.
This represents a communion of man's energy and the mountain's energy. This positive energy is important for disciplining the mind and helps worshipping visitors find inner calm and peace. Some Korean people were praying in the buildings. Of course, worship takes various forms but some common themes involve requests for comfort of mind, modesty, and a healthy family. The worshipping ritual begins in a standing position.
