The way a layman becomes a Buddhist
Taking the Three Refuges (Ti- Sarana)
      To become a Buddhist first one must go to the refuge of The Buddha, The Dhamma and The Sangha. The Buddha, The Dhamma and The Sangha are known as The Noble Triple Gem (Ti-Sarana). Going to the refuge of The Noble Triple Gem means that one places utmost confidence in The Buddha, The Dhamma and The Sangha to guide one in one's spiritual development of wholesome actions leading to enlightenment. This is done willingly and not as a command.

The Five Precepts (Panca Sīla)
        A layman, by practising the Five Precepts is able to exercise self-control over verbal and physical immoral deeds. This path of moral restraint enables one to live happily and peacefully. The Five Precepts are not commandments but are voluntarily observed and practised for one's own good and for the good of others. 
      The practitioner of the Five Precepts, take upon himself to safeguard him and others from vices. This enables a danger free, fear free, secure society which is open, happy and harmonious. Further, practising the Five Precepts is the foundation for a layperson to develop the path to enlightenment. This is because the practitioner is able to purify the mind further having brought under control the speech and body from unwholesome actions.
