Dr. Guo Yong Jin was born in Taiwan in 1955, and he started to probe the truth of the universe and reality when he was just a teenager. He spent three decades studying both religious and secular philosophies, and in 1999 following an earthquake in Taiwan, Dr. Guo realized the ultimate truth and felt a great calling to become a volunteer of the whole world. He believes humanity needs to become a community of shared life, and he hopes Mysteries of Dao De Jing (Tao Te Ching) Revealed can be an enlightening guide for fellow seekers and world volunteers.
