Śakra (Buddhism)

Śakra (Buddhism) is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Śakra (Buddhism) rather than just read about it. In short: Indra, with the epithet of Śakra (Sanskrit: शक्र Śakra; Pali: सक्क Sakka), is the ruler of the Trāyastriṃśa Heaven according to Buddhist cosmology. The name Śakra ("powerful") as an epithet of Indra is found in several verses of the Rigveda.

Reference excerpt

Indra, with the epithet of Śakra (Sanskrit: शक्र Śakra; Pali: सक्क Sakka), is the ruler of the Trāyastriṃśa Heaven according to Buddhist cosmology. The name Śakra ("powerful") as an epithet of Indra is found in several verses of the Rigveda. Indra is also referred to by the title "Śakra, Lord of the Devas" (Sanskrit: Śakro devānāṃ indraḥ; Pali: Sakko devānaṃ indo). In East Asian cultural traditions, Indra Śakra is known as Dìshìtiān (帝釋天) or Shìtí Huányīn (釋提桓因) in Chinese, as Taishakuten (帝釈天) in Japanese, as Jeseokcheon (제석천) in Korean, and as Đế Thích Thiên (帝釋天) or Thích Đề Hoàn Nhân (釋提桓因) in Vietnamese. In Chinese Buddhism, Indra Śakra is sometimes identified with the Taoist Jade Emperor (Yùhuáng Dàdì 玉皇大帝, often simplified to Yùhuáng 玉皇); both share a birthday on the ninth day of the first lunar month of the Chinese calendar (usually in February). The Trāyastriṃśa heaven in which Indra Śakra rules is located on the top of Mount Meru, imagined to be the polar center of the physical world, around which the Sun and Moon revolve. Trāyastriṃśa is the highest of the heavens in direct contact with humankind. Like all deities, Śakra is long-lived but mortal; when one Śakra dies, his place is taken by another deity who becomes the new Śakra. However, in some traditions, Śakra is either elevated to an enlightened being or a "stream-enterer" (Pali: sotāpanna) Several stories about Indra Śakra are found in the Jataka tales, as well as several suttas. Indra Śakra is married to Sujā, daughter of the chief of the asuras, Vemacitrin (Pāli Vepacitti). Despite this relationship, a state of war generally exists between the thirty-three gods and the asuras, which Indra Śakra manages to resolve with minimal violence and no loss of life. Indra Śakra is often depicted in literature as a being who consults the Buddha on matters of morality. Together with Brahmā, he is considered a dharmapala, a protector of Buddhism.

Etymology "Śakra" is a Sanskrit word meaning "mighty" or "powerful" and is used as an epithet of Indra in hymn 5.34 of the Rigveda. The related Pāli lexeme "Sakka" seems to have been the standard name of the king of heaven in Buddhist tradition.

Names

Śakra is known by several names in Buddhist texts. Some of these include:

Indra (Sanskrit; Chinese: 因陀羅; pinyin: Yīntuóluó; Japanese: Indara, Standard Tibetan: དབང་པོ་ dbang po) Mahendranīla (Sanskrit; lit. "Great Indra the Dark") Sahassākkha (Chinese: 娑婆婆; pinyin: Suōpópo; Japanese: Sababa; or 婆婆; Pópo; Japanese: Baba). Sahasrekṣaṇa (Sanskrit; Chinese: 千眼; pinyin: Qiānyǎn; lit. "Thousand Eyes") (Chinese: 天主; pinyin: Tiānzhǔ; lit. "Lord of Heaven")

Theravāda Sakka's mythology and character is expounded upon in the Pali Canon, particularly in the Sakka Saṃyutta of the Saṃyutta Nikāya. Sakka plays a significant role in several of the Jātaka tales. The commentator Buddhaghoṣa has identified Sakka as being identical to Vajrapāṇi. Thus, Sakka is identified as a Bodhisattva. In the Mahāparinibbāna Sutta (DN 16), Sakka speaks the following verse, which has become standard in Buddhist funeral rites:

Mahāyāna In the Book of Equanimity, Śakra plays a central role in the fourth koan. In the Mahāparinirvāṇa Sūtra, Śakra utters a stanza in response to the Buddha's death as a recognition of the Four Noble Truths. It is identical to the Pali formula found in the corresponding sutta.:

He is also recognized as one of the Twenty-Four Guardian Devas in Chinese Buddhist tradition.

Iconography In Southeast Asia's Theravada communities, Śakra is depicted with blue or black skin, alongside a mount, Airavata, a three-headed elephant.

Folk belief Śakra is equated with Haneullim in Korean folk religion. According to the Memorabilia of the Three Kingdoms, it is believed that Śakra is Hwanung's father. In Chinese Buddhism, some equate him with the Jade Emperor. In Mongolian Buddhism, Qormusta Tengri is syncretized with Śakra, and is believed to be involved with the creation of fire. The ceremonial name of Bangkok alludes to Śakra:

This name is composed of both Pāli and Sanskrit, prefaced with the only one Thai word, Krung, which means 'capital'. It can thus be written as: "Krung-dēvamahānagara amararatanakosindra mahindrāyudhyā mahātilakabhava navaratanarājadhānī purīramya uttamarājanivēsana mahāsthāna amaravimāna avatārasthitya shakrasdattiya vishnukarmaprasiddhi."

Popular culture Śakra makes several appearances in popular culture, including:

He is a character in the mobile game Monster Strike. He appears as a villain in the Chinese comic Fung Wan. He also appears as a villain in the manga series RG Veda. Indra Ōtsutsuki from the Naruto series is loosely based on Śakra. His younger brother's name is Asura, which plays on the myth of the battle between the deva and the asura. It is possible that Kami and Mr. Popo from the Dragon Ball series share a connection with Śakra. Mr. Popo's name is phonetically similar to the Chinese pronunciation of Sahassākkha (婆婆 Pópo), an epithet of Śakra. Kami's role as guardian deity is also similar to Śakra's relationship with the human world. This is further supported by the function of the Lookout, Kami's temple, which is reminiscent of Trāyastriṃśa heaven. Traditionally, this heaven is depicted as a flat surface on the top of Mt. Sumeru. There are thirty-two trees on the Lookout, which equate to the same number of palaces in Trāyastriṃśa (not counting the thirty-third, Śakra's palace, exemplified by the hyperbolic time chamber).

Worked examples

Example 1 — a first encounter with Śakra (Buddhism)

Start with the simplest possible case. Write down what Śakra (Buddhism) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Śakra (Buddhism) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Śakra (Buddhism) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Śakra (Buddhism)

In research: Śakra (Buddhism) appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Śakra (Buddhism) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Śakra (Buddhism) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buddhist cosmology, Buddhist gods, Indra, so understanding it makes those chapters shorter.
In everyday life: Look for Śakra (Buddhism) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
