Typical "Si" buildings are rare today. The first hall of a "Si" is the hall of Heavenly Guardians, also known as Dharma Protectors. Situated in the center of the hall, facing the front door, is Mi Le Pu Sa (Maitreya Bodhisattva) who is represented by the image of the historical monk BU Dai. Me Le Pu Sa has a big smile that conveys the idea that in order to truly learn Buddhism, one should learn to be cheerful and courteous to all. He also has a huge belly that represents fairness, flexibility, impartiality, patience and tolerance.

Standing beside Mi Le Pu Sa are the four Heavenly Guardians or Dharma Protectors. They are symbolic guardians of the practitioners of the Buddhist way. Whom do they protect? They protect us by reminding us to educate ourselves and to safeguard the proper knowledge, which we should learn. Each guardian portrays a different aspect of thought or action.

The Eastern Dharma Protector (holding a lute) symbolizes responsibility and safeguards the territory, which means that all of us are responsible for ourselves, our family, society and the country as a whole. If each of us performs our duties well, fulfilling our obligations, we support each other and ourselves as well. The Southern Dharma Protector (holding a sword) symbolizes progress and teaches us diligence. He emphasizes the importance of constantly cultivation and advancing our virtue, wisdom and knowledge, and to improve performance in ourselves and our duties. This is similar to Confucian ideas of daily self-improvement.

The Western Dharma Protector (holding a dragon or snake) symbolizes comprehensive vision and knowledge gained through exposure to the world. He represents the need to open our eyes to observe nature and man, to refine what we see and learn, and to distinguish good from ill. The Northern Dharma Protector (holding an umbrella) symbolizes comprehensive study and learning. Both teach ways of practice and how to achieve the goals in responsibility fulfillment and self-improvement. As the ancient Chinese have said:"To read ten thousand books and to travel ten-thousand miles." We read to gain more knowledge and travel to observe more effectively. We will then be able to improve ourselves and to perform our duties most effectively.

Today, people visit the Hall of Dharma Protectors to burn incense, prostrate and offer flowers and fruit praying for protection and safety. This is superstition. All the facilities, images of Buddha and Bodhisattvas and any offerings made are teaching tools designed to inspire our mind and wisdom. They also serve to remind us of the importance of being enlightened instead of deluded, virtuous instead of deviated, pure instead of polluted. There are the three principles of Buddhist teaching and practice.
