Impermanence (Pāli: अनिच्चा anicca; Sanskrit: अनित्य anitya; Tibetan: མི་​རྟག་​པ་ mi rtag pa; Chinese: 無常 wúcháng; Japanese: 無常 mujō; Korean: 무상 musang; Thai: อนิจจัง anitchang, from Pali "aniccaŋ") is one of the essential doctrines or three marks of existence in Buddhism. The term expresses the Buddhist notion that all of conditioned existence, without exception, is in a constant state of flux. The Pali word anicca literally means "inconstant", and arises from a synthesis of two separate words, 'Nicca' and the "privative particle" 'a'. Where the word 'Nicca' refers to the concept of continuity and permanence, 'Anicca' refers to its exact opposite; the absence of permanence and continuity.

Anicca or impermanence is understood by Buddhists as one of the three marks of existence, the others being dukkha (unsatisfactoriness) and anatta (non-selfhood). All things in the universe are understood by Buddhists to be characterised by these three marks of existence. According to the impermanence doctrine, human life embodies this flux in the aging process, the cycle of birth and rebirth (samsara), and in any experience of loss. This is applicable to all beings and their environs including devas (mortal gods). The Buddha taught that because conditioned phenomena are impermanent, attachment to them becomes the cause for future suffering (dukkha).

Shinzen Young (真善, Shinzen^?) is an American meditation teacher. He leads residential meditation retreats for students interested in learning the Vipassana (mindfulness) tradition of Buddhism. Although Vipassana is traditionally a Theravada technique, Shinzen was originally ordained in Japan as a monk in the Shingon (Japanese Vajrayana) tradition. He has studied and practiced extensively in other traditions, including Zen and Native American traditions.

He frequently uses concepts from mathematics as a metaphor to illustrate the abstract concepts of meditation. As a result, his teachings tend to be popular among academics and professionals. His interest in integrating meditation with scientific paradigms has led to collaborations with neuroscientists at UCLA and the University of Wisconsin, Madison. He is working on various ways to bring a secular mindfulness practice to a wider audience, using revamped terminology and techniques and automated expert systems.

Shinzen was born Steve Young in Los Angeles, California. He had a strong interest in Japanese language and Asian culture in high school, which led to him living as an exchange student in Japan. There he was exposed to Buddhism and Buddhist teachers, which eventually led him to become a monk.

Assemblage 23 is an electronic act from the United States, currently based in Seattle. It was founded in 1988 by Tom Shear who writes the music and lyrics and does the recording himself.

Prior to starting Assemblage 23, Shear experimented with music under the name Man on a Stage, beginning in the early 1980s. Most of Shear's music at this point was instrumental, as he lacked the confidence to sing; the quality of the music itself was highly questionable by his own admission. Shear eventually began to add vocals to his music; at the same time, Shear was also playing bass in a live band called the Advocates.

Assemblage 23 was officially born in 1988, after Shear experienced the industrial dance music played by an opening DJ for Depeche Mode. The style of this genre deeply impressed Shear; he believed he had finally found the sort of sound he wanted for his music. Even so, the project was more of a hobby for Shear at this point; it took until 1998 for Assemblage 23 to gather enough positive acclaim to attract the attention of record labels.

Meredith Jane Monk (born November 20, 1942 in New York) is an American composer, performer, director, vocalist, filmmaker, and choreographer. Since the 1960s, Monk has created multi-disciplinary works which combine music, theatre, and dance, recording extensively for ECM Records.

Meredith Monk is primarily known for her vocal innovations, including a wide range of extended techniques, which she first developed in her solo performances prior to forming her own ensemble. In December 1961, she appeared at the "Actor's Playhouse" in Greenwich Village (NYC) as a solo dancer in an Off Broadway children's musical theater adaptation of Charles Dickens' "A Christmas Carol," entitled "Scrooge" (music and lyrics by Norman Curtis; directed and choreographed by Patricia Taylor Curtis). In 1964, Monk graduated from Sarah Lawrence College after studying with Beverly Schmidt Blossom, and in 1968 she founded The House, a company dedicated to an interdisciplinary approach to performance.

Monk's performances have influenced many artists, including Bruce Nauman, whom she met in San Francisco in 1968. In 1978 Monk formed Meredith Monk and Vocal Ensemble (modelled after similar ensembles of musical colleagues, such as Steve Reich and Philip Glass), to explore new and wider vocal textures and forms, which often were contrasted with minimal instrumental textures. Monk began a long-standing relationship with the Walker Art Center of Minneapolis, which continues to showcase her work to this day. Pieces from this time include Dolmen Music (1979), which also was recorded for her first album released at Manfred Eicher's record label ECM in 1981.
