Mahayana (Northern/Developed Sect)Meditation
In Sravakabbumi, Asanga explained that the practitioner needs to contemplate on the impurities of the body, the sufferings of the feelings/sensation, the impermanence of thoughts, and the emptiness of all phenomena.
The Zen tradition holds that in meditation practice, notions of doctrine and teachings necessitate the creation of various notions and appearances (Skt. saṃjñā; Ch. 相, xiāng) that obscure the transcendent wisdom of each being's Buddha-nature. This process of rediscovery goes under various terms such as "introspection", "a backward step", "turning-about" or "turning the eye inward".
Sitting Meditation
Sitting meditation is called zazen, and in Chinese it is called zuòchán (坐禅), both simply meaning "sitting dhyāna". During this sitting meditation, practitioners usually assume a position such as the lotus position, half-lotus, Burmese, or seiza postures. To regulate the mind, awareness is directed towards counting or watching the breath or put in the energy center below the navel (see also anapanasati). Often, a square or round cushion placed on a padded mat is used to sit on; in some other cases, a chair may be used.
In the Soto school of Zen, meditation with no objects, anchors, or content, is the primary form of practice. The meditator strives to be aware of the stream of thoughts, allowing them to arise and pass away without interference. Considerable textual, philosophical, and phenomenological justification of this practice can be found throughout Dōgen's Shōbōgenzō, as for example in the "Principles of Zazen" and the "Universally Recommended Instructions for Zazen".
At the beginning of the Song Dynasty, practice with the koan method became popular, whereas others practiced "silent illumination." This became the source of some differences in practice between the Linji and Caodong traditions.
Intensive group practice
Zen traditions include periods of intensive group meditation in a monastery. While the daily routine in the monastery may require monks to meditate for several hours each day, during this intensive period they devote themselves almost exclusively to the practice of sitting meditation. The numerous 30–50 minute long meditation periods are interleaved with short rest breaks, meals, and sometimes, short periods of work should be performed with the same mindfulness; nightly sleep is kept to a minimum: 7 hours or less. In modern Buddhist practice in Japan, Taiwan, and the West, lay students often attend these intensive practice sessions, which are typically 1, 3, 5, or 7 days in length. These are held at many Zen centers, especially in commemoration of the Buddha's attainment of Anuttarā Samyaksaṃbodhi. One distinctive aspect of Zen meditation in groups is the use of a flat wooden slat used to keep meditators focused and awake.
Koan Practice
Zen Buddhists may practice koan inquiry during sitting meditation (zazen), walking meditation (kinhin), and throughout all the activities of daily life. Koan practice is particularly emphasized by the Japanese Rinzai school, but it also occurs in other schools or branches of Zen depending on the teaching line.
A koan (literally "public case") is a story or dialogue, generally related to Zen or other Buddhist history; the most typical form is an anecdote involving early Chinese Zen masters. These anecdotes involving famous Zen teachers are a practical demonstration of their wisdom, and can be used to test a student's progress in Zen practice. Koans often appear to be paradoxical or linguistically meaningless dialogues or questions. But to Zen Buddhists the koan is "the place and the time and the event where truth reveals itself"[44] unobstructed by the oppositions and differentiations of language. Answering a koan requires a student to let go of conceptual thinking and of the logical way we order the world, so that like creativity in art, the appropriate insight and response arises naturally and spontaneously in the mind.
Koans and their study developed in China within the context of the open questions and answers of teaching sessions conducted by the Chinese Zen masters. Today, the Zen student's mastery of a given koan is presented to the teacher in a private interview (referred to in Japanese as dokusan (独参), daisan (代参), or sanzen (参禅)). Zen teachers advise that the problem posed by a koan is to be taken quite seriously, and to be approached as literally a matter of life and death. While there is no unique answer to a koan, practitioners are expected to demonstrate their understanding of the koan and of Zen through their responses. The teacher may approve or disapprove of the answer and guide the student in the right direction. There are also various commentaries on koans, written by experienced teachers, that can serve as a guide. These commentaries are also of great value to modern scholarship on the subject.
Chanting and Liturgy
A practice in many Zen monasteries and centers is a daily liturgy service. Practitioners chant major sutras such as the Heart Sutra, chapter 25 of the Lotus Sutra (often called the "Avalokiteshvara Sutra"), the Song of the Jewel Mirror Awareness, the Great Compassionate Heart Dharani (Daihishin Dharani), and other minor mantras.
The Butsudan is the altar in a monastery where offerings are made to the images of the Buddha or Bodhisattvas. The same term is also used in Japanese homes for the altar where one prays to and communicates with deceased family members. As such, reciting liturgy in Zen can be seen as a means to connect with the Bodhisattvas of the past. Liturgy is often used during funerals, memorials, and other special events as means to invoke the aid of supernatural powers.
Chanting usually centers on major Bodhisattvas like Avalokiteshvara (see also Guan Yin) and Manjusri. According to Mahayana Buddhism, Bodhisattvas are beings who have taken vows to remain in Samsara to help all beings achieve liberation from the cycle of birth, death and rebirth. Since the Zen practitioner's aim is to walk the Bodhisattva path, chanting can be used as a means to connect with these beings and realize this ideal within oneself. By repeatedly chanting the Avalokiteshvara sutra (観世音菩薩普門品 Kanzeon Bosatsu Fumonbon?)(chapter 25 of the Lotus Sutra), for example, one instills the Bodhisattva's ideals into ones mind. The ultimate goal is given in the end of the sutra, which states, "In the morning, be one with Avalokiteshvara; in the evening, be one with Avalokiteshvara". Through the realization of emptiness and the Mahayana notion that all things have Buddha-nature, one understands that there is no difference between the cosmic bodhisattva and oneself. The wisdom and compassion of the Bodhisattva one is chanting to is seen to equal the inner wisdom and compassion of the practitioner. Thus, the duality between the subject and the object, the practitioner and the Bodhisattva, the chanter and the sutra is ended.
