In a stupa, there are giant pairs of eyes looking out from the four sides of the main tower known as Buddha eyes and wisdom eyes. The eyes of the Buddha in the stupa symbolize the all-seeing ability of the Buddha. According to Buddhism, we can say that if we are wise, we can see beyond material things. We can then see the truth. People are facing depression, anxiety and suffering which can be the darkness of life. Only wisdom can lead them out of the darkness.
