Noble Eightfold Path in the context of "Udayana (king)"

Buddhism, also known as Buddha-dharma and Dharmavinaya, is an Indian religion and philosophy based on teachings attributed to the Buddha, a śramaṇa and religious teacher who lived in the 6th or 5th century BCE. It is the world's fourth-largest religion, with about 320 million followers, known as Buddhists, who comprise 4.1% of the global population. It arose in the eastern Gangetic plain as a śramaṇa movement in the 5th century BCE, and gradually spread throughout much of Asia. Buddhism has subsequently played a major role in Asian culture and spirituality, eventually spreading to the West in the 20th century.

According to tradition, the Buddha instructed his followers in a path of cultivation that leads to awakening and full liberation from dukkha (lit. 'suffering'; 'unease', 'unsatisfactoriness') by attaining nirvana, the 'blowing out' (extinguishing) of the passions. He regarded this path as a Middle Way between extreme asceticism and sensory indulgence, and also between the extremes of eternalism and nihilism. Teaching that dukkha arises alongside attachment or clinging, the Buddha advised meditation practices and ethical precepts, rooted in non-harming. Widely observed teachings include the Four Noble Truths, the Noble Eightfold Path, and the doctrines of dependent origination, karma, and the three marks of existence. Other commonly observed elements include the Triple Gem, the taking of monastic vows, and the cultivation of perfections (pāramitā).

Siddhartha Gautama, most commonly referred to as the Buddha (lit. 'the awakened one'), was a wandering ascetic and religious teacher who lived in South Asia during the 6th or 5th century BCE and founded Buddhism. According to Buddhist legends, he was born in Lumbini, in what is now Nepal, to royal parents of the Shakya clan, but renounced his home life to live as a wandering ascetic. After leading a life of mendicancy, asceticism, and meditation, he attained nirvana at Bodh Gaya in what is now India. The Buddha then wandered through the lower Indo-Gangetic Plain, teaching and building a monastic order (sangha). Buddhist tradition holds he died in Kushinagar and reached parinirvana ("final release from conditioned existence").

According to Buddhist tradition, the Buddha taught a Middle Way between sensual indulgence and severe asceticism, leading to freedom from ignorance, craving, rebirth, and suffering. His core teachings are summarised in the Four Noble Truths and the Noble Eightfold Path, a training of the mind that includes ethical training and kindness toward others, and meditative practices such as sense restraint, mindfulness, dhyana (meditation proper). Another key element of his teachings are the concepts of the five skandhas and dependent origination, describing how all dharmas (both mental states and concrete 'things') come into being, and cease to be, depending on other dharmas, lacking an existence on their own (svabhava).

Nirvana or nibbana (Sanskrit: निर्वाण; IAST: nirvāṇa; Pali: nibbāna) is the extinguishing of the passions, the "blowing out" or "quenching" of the activity of the grasping mind and its related suffering, stresses, and unease. Nirvana is the goal of many Buddhist paths, and leads to the soteriological release from dukkha ('suffering') and rebirths in saṃsāra. Nirvana is part of the Third Truth on "cessation of dukkha" in the Four Noble Truths, and the "summum bonum of Buddhism and goal of the Eightfold Path."

In all forms of Buddhism, Nirvana is regarded as the highest or supreme religious goal. It is often described as the unconditioned or uncompounded (Skt.: asaṃskṛta, Pali: asankhata), meaning it is beyond all forms of conditionality — not subject to change, decay, or the limitations of time and space. Nirvana is typically seen as being outside the realm of dependent arising (pratītyasamutpāda), representing a truth that transcends cause and effect, as well as all conventional dualities such as existence and non-existence, or life and death. Nirvana is also said to transcend all conceptual frameworks, being beyond the grasp of ordinary human perception.

The Middle Way or Middle Path (Pali: Majjhimāpaṭipadā; Sanskrit: Madhyamāpratipada) as well as "teaching the Dharma by the middle" (majjhena dhammaṃ deseti) are common Buddhist terms used to refer to two major aspects of the Dharma, that is, the teaching of the Buddha. The first phrasing, the Middle Way, refers to a spiritual practice that steers clear of both extreme asceticism and sensual indulgence. This spiritual path is defined as the Noble Eightfold Path that leads to awakening. The second formulation, "teaching the Dharma by the middle," refers to how the Buddha's Dharma (Teaching) approaches ontological issues of existence and personal identity by avoiding eternalism (or absolutism) and annihilationism (or nihilism).

Buddhist ethics are traditionally based on the enlightened perspective of the Buddha. In Buddhism, ethics or morality are understood by the term śīla (Sanskrit: शील) or sīla (Pāli). Śīla is one of three sections of the Noble Eightfold Path. It is a code of conduct that emulates a natural inborn nature that embraces a commitment to harmony, equanimity, and self-regulation, primarily motivated by nonviolence or freedom from causing harm. It has been variously described as virtue, moral discipline uprightness and precept, skillful conduct.

In contrast to the english word "morality" (i.e., obedience, a sense of obligation, and external constraint), Sīla is a resolve to connect with what is believed to be our innate ethical compass. It is an intentional ethical behaviour that is refined and clarified through walking the path toward liberation. Within some traditions, the true adversary is our ignorance, our clinging to beliefs, complexes and our misguided perceptions. As such, behavior is not viewed as good or evil but as skillful or unskillful.

In Buddhism, the Four Noble Truths (Sanskrit: चत्वार्यार्यसत्यान, romanized: catvāryāryasatyāni; Pali: cattāri ariyasaccāni; "The Four arya satya") are "the truths of the noble one (the Buddha)," a statement of how things really are when they are seen correctly. The four truths are

• dukkha (not being at ease, 'suffering', from dush-stha, standing unstable). Dukkha is an innate characteristic of transient existence; nothing is forever, this is painful;
• samudaya (origin, arising, combination; 'cause'): together with this transient world and its pain, there is also thirst (desire, longing, craving) for and attachment to this transient, unsatisfactory existence;
• nirodha (cessation, ending, confinement): the attachment to this transient world and its pain can be severed or contained by the confinement or letting go of this craving;
• marga (road, path, way): the Noble Eightfold Path is the path leading to the confinement of this desire and attachment, and the release from dukkha.

The four truths appear in many grammatical forms in the ancient Buddhist texts, and are traditionally identified as the first teaching given by the Buddha. While often called one of the most important teachings in Buddhism, they have both a symbolic and a propositional function. Symbolically, they represent the awakening and liberation of the Buddha, and of the potential for his followers to reach the same liberation and freedom that he did. As propositions, the Four Truths are a conceptual framework that appear in the Pali canon and early Hybrid Sanskrit Buddhist scriptures, as a part of the broader "network of teachings" (the "dhamma matrix"), which have to be taken together. They provide a conceptual framework for introducing and explaining Buddhist thought, which has to be personally understood or "experienced".

In Buddhism, the three marks of existence are three characteristics (Pali: tilakkhaṇa; Sanskrit: त्रिलक्षण trilakṣaṇa) of all existence and beings, namely anicca (impermanence), dukkha (commonly translated as "suffering" or "cause of suffering", "unsatisfactory", "unease"), and anattā (without a lasting essence). The concept of humans being subject to delusion about the three marks, this delusion resulting in suffering, and removal of that delusion resulting in the end of dukkha, is a central theme in the Buddhist Four Noble Truths, the last of which leads to the Noble Eightfold Path.

The intersections of morality and religion involve the relationship between religious views and morals. It is common for religions to have value frameworks regarding personal behavior meant to guide adherents in determining between right and wrong. These include the Triple Gems of Jainism, Islam's Sharia, Catholicism's Catechism, Buddhism's Noble Eightfold Path, and Zoroastrianism's "good thoughts, good words, and good deeds" concept, among others. Various sources - such as holy books, oral and written traditions, and religious leaders - may outline and interpret these frameworks. Some religious systems share tenets with secular value-frameworks such as consequentialism, freethought, and utilitarianism.

Religion and morality are not synonymous. Though religion may depend on morality,and even develop alongside morality,morality does not necessarily depend upon religion, despite some making "an almost automatic assumption" to this effect. According to The Westminster Dictionary of Christian Ethics, religion and morality "are to be defined differently and have no definitional connections with each other. Conceptually and in principle, morality and a religious value system are two distinct kinds of value systems or action guides." In the views of some, morality and religion can overlap.One definition sees morality as an active process which is, "at the very least, the effort to guide one's conduct by reason, that is, doing what there are the best reasons for doing, while giving equal consideration to the interests of all those affected by what one does."
