The Three Gems are the Gem of the Buddha, the enlightened one, the Gem of Dhamma, the teachings given by the Buddha, and the Gem of Sangha, the Order of the monastic disciples. These three and called gems because they can lead people to stop doing evil and to perform kindness, to free themselves from suffering and to gain happiness. The title of “The Three Gems” also shows the great value placed on them. When the Buddha initially turned the wheel of Dharma, Kongdanna and others, five of them in all, followed the Buddha, renounced lay life and became the Buddha’s disciples, thus forming the Sangha Order. Therefore, the Three Gems have been cherished since that time. (From Essentials of Buddhism: Questions and Answers)
