    Bodhisattva

    In Mahayana Buddhism, bodhisattva is the Sanskrit term for anyone who, motivated by great compassion, has generated bodhicitta, which is a spontaneous wish to attain buddhahood for the benefit of all sentient beings. Bodhisattvas are a popular subject in Buddhist art.

    Origins and outlines

    In early Indian Buddhism, the term bodhisattva was primarily used to refer specifically to Gautama Buddha in his former life. The Jataka tales, which are the stories of the Buddha's lives, depict the various attempts of the bodhisattva to embrace qualities like self-sacrifice and morality.

    From this Jataka tales, Bodhisattva originally meant the Buddhism practitioner of austerities that surpassed Śrāvakayana and Pratyekabuddhayana by far and completed Bodhisattvayana. Mount Potalaka, for example, is one of Bodhisattvayana. The name for practitioners who do not yet reach Bodhisattvayana was not fixed, but the terms Śrāvaka-Bodhisattva (聲聞菩薩) or Pratyekabuddha-Bodhisattva (縁覚菩薩) already appear in Āgama which is sutras of early Indian Buddhism.

    Marketing mix

    The term "marketing-mix" was first coined by Neil Borden, the president of the American Marketing Association in 1953. It is still used today to make important decisions that lead to the execution of a marketing plan. The various approaches that are used have evolved over time, especially with the increased use of technology.

    The marketing mix is a business tool used in marketing and by marketers. The marketing mix is often crucial when determining a product or brand's offer, and is often associated with the four Ps: price, product, promotion, and place. In service marketing, however, the four Ps are expanded to the seven Ps or Seven Ps to address the different nature of services.

    In the 1990s, the concept of four C's was introduced as a more customer-driven replacement of four P's. There are two theories based on four Cs: Lauterborn's four Cs (consumer, cost, communication, convenience), and Shimizu's four Cs (commodity, cost, communication, channel).

    In 2012, a new four P's theory was proposed with people, processes, programs, and performance.

    P.S. (film)

    p.s. is a 2004 drama film directed by Dylan Kidd. The screenplay by Kidd and Helen Schulman is based on Schulman's 2001 novel p.s. The film stars Laura Linney and Topher Grace.

    Plot synopsis

    Thirty-nine-year old divorcée Louise Harrington (Linney) works in the admissions office at Columbia University School of the Arts. She is unnerved when she receives an application from F. Scott Feinstadt (Grace), the same name of her high school sweetheart who was killed in a car crash, and calls the student to arrange an interview. His appearance, mannerisms, and painting style closely resemble those of her former love, and she begins to suspect the young artist may be the reincarnation of her old flame. Hours after meeting, the two embark upon an affair. Also complicating Louise's life are her relationship with her ex-husband Peter (Gabriel Byrne), who confesses he is learning to cope with a sex addiction that, unknown to her, plagued their marriage; her ne'er-do-well brother Sammy (Paul Rudd), who is favored by their mother Ellie (Lois Smith) despite his shortcomings; and her best friend Missy (Marcia Gay Harden), who stole the original Scott from Louise before his death and seems intent on doing the same with the contemporary version.

    P.S. (Doctor Who)

    "P.S." is a mini episode of the seventh series of Doctor Who, written by Chris Chibnall. Set after the departure of Amy Pond and Rory Williams in "The Angels Take Manhattan", it depicts a letter that Rory sent to his father Brian explaining why he and Amy are not returning. This episode was dubbed "the scene that was never shot", as it was released in complete storyboard drawings.

    Synopsis

    The final scene from "The Power of Three" is shown, before the titles.

    Afterwards, in complete drawing format, Brian is shown watering the plants, when there is a knock at the door. A man, Anthony, from New York, hands Brian a letter. Anthony tells Brian that he'll wait indoors until he has read it.

    Brian sits down and reads the letter, which is from his son Rory. It explains that Brian will never be able to see him or Amy again, and he apologises. Rory also explains that the person who delivered the letter is Brian's grandson, Anthony Brian Williams, whom Amy and Rory adopted in 1946.

    After Brian reads the letter, he walks out to Anthony, who offers a handshake. The two then embrace in a hug as the episode closes.
