There are eight Bodhisattva (Enlightened being) who protect the 12 Chinese Horoscope signs, with each deity protecting one (or two) Zodiac animals. The patron Horoscope Guardian deity of the Dragon and Snake is Samantabhadra. Carrying your Guardian deity amulet card close to you not only protects you from harm, it is also believed to help remove obstacles in your path, bring good fortune, attract good health and expel disasters.
Samantabhadra is the Bodhisattva of Universal Goodness or Bodhisattva of Great Conduct. He is the patron of the Lotus Sutra who encourages people to diligently practice the Buddhist precepts of moral conduct, patience, devotion and charity. He is believed to bring longevity luck and unexpected good news to Dragon and Snake-born and help dispel misfortunes brought by spirit harm.
The Dependent Arising mantra printed on the other side of the card is said to help actualize all your aspirations and wishes in life.
