Turbinella Pyrum
''Turbinella pyrum'', common names the chank shell, sacred chank or chank, also known as the divine conch, sometimes referred to simply as a conch, is a species of very large sea snail with a gill and an operculum, a marine gastropod mollusk in the family Turbinellidae. This species occurs in the Indian Ocean. The name "chank" for the shell of this species is derived from the Indian word ''shankha'', the divine conch. The old generic name was ''Xancus''. The Dutch used to call them ''chianco''. Distribution This species is found mainly in the Indian Ocean. Description The shell of this species is massive, with three or four prominent columellar plicae. It is usually pure white under a heavy brown periostracum, but it can also be a pale apricot color. It can sometimes be dotted with dark brown. Shells of the lightning whelk (''Sinistrofulgur sp.''), a normally left-handed western Atlantic Ocean genus, are sometimes sold in imitation of the rare left-handed shells of t ...

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised.

Dakshinavarti Shankh
Dakshinavarti shankha (), also referred to as Valampuri shankhu () and Sri Lakshmi shankha () is a sacred Hindu conch. It refers to the shell of a large sea snail from the Indian Ocean (a shell of the species ''Turbinella pyrum''), but one that has a rare reverse-turning spiral. The shankha is held with the spout (siphonal canal) pointed up; its spiral twists rightwards rather than the more common form, which twists leftwards. Terminology In scientific usage a ''dextral'' ( la, dexter, right) shell has the opening on the right, when viewed with the spire . The opposite is ''sinistral'' ( la, sinister, left). This is consistent with the terms for right- handed screws in engineering and physics. Most species of sea snail are dextral. Within a typically-dextral species, rare individuals may develop sinistral coiling. In religious usage, the ( sacred conch shell) is displayed spire . In this orientation, a common dextral shell has its opening on the left ( sa, vamavarti). It is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trumpet
The trumpet is a brass instrument commonly used in classical and jazz ensembles. The trumpet group ranges from the piccolo trumpet—with the highest register in the brass family—to the bass trumpet, pitched one octave below the standard B or C trumpet. Trumpet-like instruments have historically been used as signaling devices in battle or hunting, with examples dating back to at least 1500 BC. They began to be used as musical instruments only in the late 14th or early 15th century. Trumpets are used in art music styles, for instance in orchestras, concert bands, and jazz ensembles, as well as in popular music. They are played by blowing air through nearly-closed lips (called the player's embouchure), producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century, trumpets have primarily been constructed of brass tubing, usually bent twice into a rounded rectangular shape. There are many distinc ...

Spire (mollusc)
A spire is a part of the coiled shell of molluscs. The spire consists of all of the whorls except for the body whorl. Each spire whorl represents a rotation of 360°. A spire is part of the shell of a snail, a gastropod mollusc, a gastropod shell, and also the whorls of the shell in ammonites, which are fossil shelled cephalopods. In textbook illustrations of gastropod shells, the tradition (with a few exceptions) is to show most shells with the spire uppermost on the page. The spire, when it is not damaged or eroded, includes the protoconch (also called the nuclear whorls or the larval shell), and most of the subsequent teleoconch whorls (also called the postnuclear whorls), which gradually increase in area as they are formed. Thus the spire in most gastropods is pointed, the tip being known as the "apex". The word "spire" is used, in an analogy to a church spire or rock spire, a high, thin, pinnacle. The "spire angle" is the angle, as seen from the apex, at which a spire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eight Auspicious Symbols
The Ashtamangala is a sacred suite of ''Eight Auspicious Signs'' endemic to a number of religions such as Hinduism, Jainism, and Buddhism. The symbols or "symbolic attributes" () are yidam and teaching tools. Not only do these attributes (or energetic signatures) point to qualities of enlightened mindstream, but they are the investiture that ornaments these enlightened "qualities" (Sanskrit: ''guṇa''; ). Many cultural enumerations and variations of the Ashtamangala are extant. In Buddhism Tibetan Buddhists make use of a particular set of eight auspicious symbols, ''ashtamangala'', in household and public art. Some common interpretations are given along with each symbol although different teachers may give different interpretations: Conch The right-turning white conch shell (Sanskrit: ; ) represents the beautiful, deep, melodious, interpenetrating and pervasive sound of the dharma, which awakens disciples from the deep slumber of ignorance and urges them to accomplish ...

Buddhism
Buddhism ( , ), also known as Buddha Dharma and Dharmavinaya (), is an Indian religion or philosophical tradition based on teachings attributed to the Buddha. It originated in northern India as a -movement in the 5th century BCE, and gradually spread throughout much of Asia via the Silk Road. It is the world's fourth-largest religion, with over 520 million followers (Buddhists) who comprise seven percent of the global population. The Buddha taught the Middle Way, a path of spiritual development that avoids both extreme asceticism and hedonism. It aims at liberation from clinging and craving to things which are impermanent (), incapable of satisfying ('), and without a lasting essence (), ending the cycle of death and rebirth (). A summary of this path is expressed in the Noble Eightfold Path, a training of the mind with observance of Buddhist ethics and meditation. Other widely observed practices include: monasticism; " taking refuge" in the Buddha, the , and the ; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hinduism
Hinduism () is an Indian religion or '' dharma'', a religious and universal order or way of life by which followers abide. As a religion, it is the world's third-largest, with over 1.2–1.35 billion followers, or 15–16% of the global population, known as Hindus. The word ''Hindu'' is an exonym, and while Hinduism has been called the oldest religion in the world, many practitioners refer to their religion as '' Sanātana Dharma'' ( sa, सनातन धर्म, lit='the Eternal Dharma'), a modern usage, which refers to the idea that its origins lie beyond human history, as revealed in the Hindu texts. Another endonym is ''Vaidika dharma'', the dharma related to the Vedas. Hinduism is a diverse system of thought marked by a range of philosophies and shared concepts, rituals, cosmological systems, pilgrimage sites, and shared textual sources that discuss theology, metaphysics, mythology, Vedic yajna, yoga, agamic rituals, and temple building, among other to ...

Hindu Priest Blowing Conch During Punja
Hindus (; ) are people who religiously adhere to Hinduism.Jeffery D. Long (2007), A Vision for Hinduism, IB Tauris, , pages 35–37 Historically, the term has also been used as a geographical, cultural, and later religious identifier for people living in the Indian subcontinent. The term ''"Hindu"'' traces back to Old Persian which derived these names from the Sanskrit name ''Sindhu'' (सिन्धु ), referring to the river Indus. The Greek cognates of the same terms are "''Indus''" (for the river) and "''India''" (for the land of the river). The term "''Hindu''" also implied a geographic, ethnic or cultural identifier for people living in the Indian subcontinent around or beyond the Sindhu (Indus) River. By the 16th century CE, the term began to refer to residents of the subcontinent who were not Turkic or Muslims. Hindoo is an archaic spelling variant, whose use today is considered derogatory.

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Lightning Whelk
''Sinistrofulgur perversum'', the lightning whelk, is an edible species of very large predatory sea snail or whelk, a marine gastropod mollusc in the family Busyconidae, the busycon whelks. This species has a left-handed or sinistral shell. It eats mostly bivalves. There has been some disagreement about the correct scientific name for this species, which has been confused with '' Sinistrofulgur sinistrum'' Hollister, 1958, and ''Busycon contrarium'' (Conrad, 1840), which is an exclusively fossil species.J. Wise, M. G. Harasewych, R. T. Dillon Jr. (2004). Population divergence in the sinistral whelks of North America, with special reference to the east Florida ecotone (PDF; 673 kB)''. Marine Biology 145, pp. 1167–1179.
