Four stages of enlightenment in the context of "Bodhi"

Saṅgha or saṃgha (IPA: [sɐŋɡʱɐ]) is a term meaning "association", "assembly", "company" or "community". In a political context, it was historically used to denote a governing assembly in a republic or a kingdom, and for a long time, it has been used by religious associations, including Buddhists, Jains and Sikhs. Given this history, some Buddhists have stated that the tradition of the sangha represents humanity's oldest surviving democratic institution.

In Buddhism, sangha refers to the monastic communities of bhikkhu (monks) and bhikkhuni (nuns). These communities are traditionally referred to as the bhikkhu-sangha or the bhikkhuni-sangha. As a separate category, those Buddhists who have attained any of the four stages of enlightenment, whether or not they are members of the monastic community, are referred to as the āryasaṅgha ("noble Sangha").

Satipatthana (Pali: Satipaṭṭhāna; Sanskrit: smṛtyupasthāna) is a central practice in the Buddha's teachings, meaning "the establishment of mindfulness" or "presence of mindfulness", or alternatively "foundations of mindfulness", aiding the development of a wholesome state of mind. In Theravada Buddhism, applying mindful attention to four domains, the body, feelings, the mind, and key principles or categories of the Buddha's teaching (dhammās), is thought to aid the elimination of the five hindrances and the development of the seven aspects of wakefulness.

The Satipatthana Sutta is probably the most influential meditation text in modern Theravada Buddhism, on which the teachings of the Vipassana movement are based. While these teachings are found in all Buddhist traditions, modern Theravada Buddhism and the Vipassana Movement are known especially for promoting the practice of satipaṭṭhāna as developing mindfulness to gain insight into impermanence, thereby reaching a first state of liberation. In the popular understanding, mindfulness has developed into a practice of bare awareness to calm the mind.
