Nine stages of decay

The contemplation of the nine stages of a decaying corpse is a Buddhist meditational practice in which the practitioner imagines or observes the gradual decomposition of a dead body. Along with paṭikūlamanasikāra, this type of meditation is one of the two meditations on "the foul" or "unattractive" (aśubha). The nine stages later became a popular subject of Buddhist art and poetry. In Japan, images of the stages are called lit. 'nine-phase pictures' (九相図) and became related to aesthetic ideas of impermanence.

Early instances of the nine stages of decay can be found in the, (–20 BC) the "Sutra on the Contemplation of the Oceanlike Buddha," and the "Discourse on the Great Wisdom"  by Nagarjuna (c.  150–250 AD). The stages listed in the spread to Japan, probably through Chinese Tiantai writings including the  of Zhiyi (438–497 AD), and influenced medieval Japanese art and literature.

The setting for the nine stages is outdoors, where a corpse would be left exposed to decay in a field, graveyard, or charnel ground. The exact stages included vary between sources. The refers to the stages as the nine  अशुभसंज्ञा lit. 'nine horrible notions,' and lists them as follows:
 * 1) distension
 * 2) rupture
 * 3) exudation of blood
 * 4) putrefaction
 * 5) discolouration and desiccation
 * 6) consumption by animals and birds
 * 7) dismemberment
 * 8) reduction to bones
 * 9) parching to dust

History
Various techniques of meditation on the process of bodily decay date back to early Buddhism, originating in India. A related meditation involves ten stages of decay. Early lists of nine stages of decay can be found in the "Sutra on the Contemplation of the Oceanlike Buddha," and the "Discourse on the Great Wisdom"   Different purposes have been assigned to the contemplation of the nine stages of a decaying corpse, and the details of the practice transformed over time.

Buddhist monks used the contemplation of a decaying corpse as a monastic practice to reduce sensual desire. In one Japanese tale, a monk called Genpin who has fallen in love with a chief councillor's wife overcomes this desire by imagining the woman's body decaying, and thus attains enlightenment by understanding the nature of the body. In as much as the practice served to the reduce sexual desire of a male practitioner, the corpse in question tended to be female. However, the nine stages were also used to reduce one's attachment to one's own body, and women themselves were encouraged to participate in the contemplation of their bodily impurity. According to some Theravāda sources such as the, the practitioner must seek a corpse of theirs own sex to contemplate, as doing otherwise would be unchaste. The emphasises that the differences between men and women are obscured even by the first stage of decay. The corpses in are explicitly female.

In some texts, the contemplation of different phases is recommended for the elimination of different aspects of lust for the body. For example, the recommends phases 8 and 9 to eliminate the "lust for touch," but phases 3, 4, and 5 for the "lust for colours." As well as eliminating raga (Buddhism) (lust), the claims the practice may reduce dvesha (Buddhism) (hatred) and moha (Buddhism) (delusion), the other two of the three poisons in Buddhism.

Buddhist sources also suggest that real corpses were originally observed as part of the practice, without the practitioner relying on pure imagination. This was possible in cultural contexts where corpses were left exposed in graveyards and fields. With training, the image could be retained and summoned at will, as in the tale of Genpin above. Later, pictorial aids developed in China, leading to the development of as an art form in Japan. gained aesthetic significance in addition to their meditative function as impermanence (無常 ) was already a major feature of Japanese art and literature.

Pictorial representations
There is literary evidence of pictorial representations of the nine stages of decay from China during the Tang dynasty, including Baoji's poem Contemplation on the Mural of the Nine Stages of a Decaying Corpse (c. 618-907 AD). Japanese images of the nine stages, called, date from the 13th century. There are a large number of still being used in religion in Japan,  and Japanese artists such as Fuyuko Matsui have continued the theme of the nine stages into the 21st century.

vary in the presentation of their subjects. Some such as the Jindou fujou souzu (人道不浄相図) present the decay of the female corpse in the context of the nature, "amidst a world of seasonal trees, flowers, and other flora." Others, including one very early example in the collection, depict the stages against a blank background with high precision, "diagrammatic in [their] presentation."

were probably shown to laypeople for the purpose of teaching the doctrine of impermanence in e-toki sessions, and displayed during the Obon festival.

Paintings of Ono no Komachi
Although the subjects of  are typically anonymous noblewomen, there are many that are explicitly intended to depict the Heian Waka (poetry) poet Ono no Komachi (小野小町). These depictions of Komachi are related to a tradition of literature that emphasises the contrast between her physical beauty during her youth, and her ageing and poverty at the end of her life. Such tales of Komachi's life, called Komachi densetsu (小町伝説) are a common subject of Noh plays including Kayoi Komachi (通小町), Sekidera Komachi (関寺小町), and Sotoba Komachi (卒塔婆小町).

In contemporary art
The of Kinbaku painter Seiu Itou (1882–1961) have been linked to the modern erotic grotesque style (エログロ). Fuyuko Matsui's recent "New kusōzu" series was inspired by the traditional painting genre, but also founded honestly on the reality of being a human being and a woman in the world today, intending to transcend a mere adaptation of a classical theme and truly realise a contemporary kusōzu sequence.

In poetry
The nine stages of decay have featured as the subject of several Chinese and Japanese poems. In Japan there are two main poems, attributed to Kuukai (774 – 835), founder of Shingon Buddhism, and Su Tongpo (1037 – 1101), a Song dynasty politician.

The Su Tongpo poem links the impermanence of the human form to changing natural and seasonal imagery. For example, the second verse, distension, describes the deceased's hair becoming entangled with grass roots:

Misogyny
The nine stages of decay, and in particular, have been described as a manifestation of the misogyny inherent to some schools of Buddhism, in which women are situated as mere objects of contemplation, reinforcing the belief that women have a lesser ability to achieve Buddhahood than men. During the edo period, such ideas of the spiritual inferiority of women were used to indoctrinate the three obediences into women and girls. This analysis has been criticised with reference to teachings that posit that women have Buddha nature precisely because of their impurity. The tales of Empress Danrin and Empress Koumyou provide examples of women who willingly planned to expose their decaying bodies to the public as an act of Buddhist devotion, in the hope that "sentient beings in the Latter Days of the Buddhist Law should be awakened through exposure to the impure human condition."

Paintings from The death of a noble lady and the decay of her body
The death of a noble lady and the decay of her body is a series of paintings in watercolor, produced in Japan around the 18th century. The subject of the paintings is thought to be Ono no Komachi.

There are nine paintings, including a pre-death portrait, and a final painting of a memorial structure:
