Buddhists "take refuge" in, or to "go for refuge" to, the Three Jewels or Triple Gem, (aka the "Three Refuges"). This can be done formally in lay and monastic ordination ceremonies.
The Three Jewels general signification is:
Refuge in the Triple Gem is common to all major schools of Buddhism.
Faith is an important teaching element in both Theravada and Mahayana traditions. In contrast to perceived Western notions of faith, faith in Buddhism arises from accumulated experience and reasoning.
In the Kalama Sutra, the Buddha explicitly argues against simply following authority or tradition, particularly those of religions contemporary to the Buddha's time. There remains value for a degree of trusting confidence and belief in Buddhism, primarily in the spiritual attainment and salvation or enlightenment. Faith in Buddhism centres on belief in the Three Jewels.
Buddhism /ˈbudɪzəm/ is a nontheistic religion or philosophy (Sanskrit: धर्म dharma; Pali: धम्म dhamma) that encompasses a variety of traditions, beliefs and spiritual practices largely based on teachings attributed to Gautama Buddha, commonly known as the Buddha ("the awakened one"). According to Buddhist tradition, the Buddha lived and taught in the eastern part of the Indian subcontinent,present-day Nepal sometime between the 6th and 4th centuries BCE. He is recognized by Buddhists as an awakened or enlightened teacher who shared his insights to help sentient beings end their suffering through the elimination of ignorance and craving. Buddhists believe that this is accomplished through the direct understanding and perception of dependent origination and the Four Noble Truths.
Two major extant branches of Buddhism are generally recognized by scholars: Theravada ("The School of the Elders") and Mahayana ("The Great Vehicle"). Vajrayana, a body of teachings attributed to Indian siddhas, may be viewed as a third branch or merely a part of Mahayana. Theravada has a widespread following in Sri Lanka and Southeast Asia. Mahayana which includes the traditions of Pure Land, Zen, Nichiren Buddhism, Shingon, and Tiantai (Tendai) is found throughout East Asia. Tibetan Buddhism, which preserves the Vajrayana teachings of eighth century India, is practiced in regions surrounding the Himalayas, Mongolia and Kalmykia. Buddhists number between an estimated 488 million and 535 million, making it one of the world's major religions.
