bet365 offers are scattered around the world，includes India、Pakistan、Nepal、Myanmar、Afghanistan、Libraries in Tibet, Xinjiang and other countries and regions in China、Museum、Temple、Grotto，There are also manuscripts in private collections、Inscriptions, etc.。Some bet365 offers have been published or digitized，Most of them are still in their original, unorganized state。

The organization bet365 offers texts aims to collect the original Sanskrit texts、Save、Fixed、Addendum、Classification、Cataloging、Edit、Proofreading、Digitalization, etc.，To facilitate translation by Sanskrit scholars、Comment、Reconsideration、Research and other work。Therefore, the compilation bet365 offers texts is the foundation of Sanskrit research，Professional knowledge involving many disciplines and fields，such as Indian paleography、Ancient History、Historical Archeology、History, geography, etc.。

First，The discipline most closely related to the compilation bet365 offers texts is Indian paleography。The older the font，The more difficult it is to recognize for today’s people。Compilation of original Chinese classics，Requires extensive knowledge of paleography。The same is true for the compilation of original Sanskrit texts。Around 300 BC，Numerous writing systems already exist in India。Two Jain scriptures mention 18 fonts in use at that time，The Sanskrit version of "The Game of Magical Powers" lists 64 fonts that existed during the time of Buddha。Some fonts in Jain and Buddhist literature overlap，4 of them have been successfully identified，A writing system considered to be historically real。First of all, the originator of the existing Indian writing system-Bharamiya，Then there is donkey lip style (also translated as "Kha Luwen", etc.)。Sanskrit characters as pinyin characters，Borrowed from Egyptian hieroglyphics，On the basis of the Aramaic alphabet, it has developed step by step from Brahma and Assy to the present，In certain historical periods, writing systems using Pinyin letters (such as the Greek alphabet) were also used and even written with Chinese phonetic alphabets，These development trends of paleography，Become a compilation bet365 offers texts、Dating、Reading、Key issues in the interpretation process。

Secondly，The development of Indian paleography or bet365 offers fonts，Also related to ancient Indian history、History and geography are inseparable。For example，Bharamiya is the text used on Ashoka’s stone carvings，Time around 3rd century BC。Gupta body developed from Brahmi body，Also known as the Mystery of Gupta or the late Mystery of Gupta，Around 4th-6th century，Basically covers the reign of the Gupta Dynasty in India。City，Also known as Beicheng style，is the central and eastern Indian variant of Gupta，First seen in the Gujarat region from the 1st to the 4th century，Widely used in the 7th century and gradually developed into Devanagari script (about 7th century to present) and Xicheng script (also translated as "Nandi City script", etc.，about 8th century to present), etc.。Sittan body also developed from Gupta body，Also known as Siddam’s mother，Around late 6th century to 12th century。Between these bet365 offers fonts，Existing relationship of inheritance，There are overlapping parts，Both and history、Region、Society、Cultural connection，To some extent, it transcends history、Region, etc.。

Finally，There are often many variations of these bet365 offers fonts，And due to the use of different writing tools or writing (engraving) on ​​different materials，And show a different look。For example，Buddhists and Brahmins in North India often use the inner bark of oiled and polished Himalayan birch (also known as "rough birch") to write bet365 offers classics，The time is approximately after Alexander’s Eastern Campaign and before the Mughal Empire，The area spread from northwest India to the entire India except southern India。bet365 offers Medium，The words "bhūrja" and "writing material" (lekhana) are even interchangeable。During the Mughal Empire，Papermaking introduced to India，The art of oiling and polishing birch bark was lost in Kashmir。And in Andhra region，Some government or private records are written on starched cotton cloth。Businessmen in Kannada region still use cotton documents covered with tamarind pulp，Blackened with charcoal，Write in chalk or talc，The writing is white or black，Even silk cloth was used for writing。

Wooden boards have been used to write Buddhist Tibetan documents since early times，Wooden writing boards are mentioned in the Jataka and other documents，There is also evidence of writing literary works on wooden boards。Bamboo slices are also used as ultimatums to write the names of Buddhist monks。According to Tandin's "The Biography of the Ten Princes"，The prince took off his armor and drew a scene of himself kneeling with his hands together to woo the sleeping princess on a piece of wood coated with gum，With a love poem。A large number of wooden wooden documents coated with gum were unearthed in Myanmar。There is a wooden scroll in the Bodleian Library at Oxford University，From the Assam region in northeastern bet365 offers。And in northwest bet365 offers，The lower class Indian people still use chalk to copy religious scriptures on wooden boards。Supandu’s "The Legend of Immortals" mentions writing on animal skins。Indian characters can be seen on an animal skin document unearthed in Kashgar, Xinjiang, China, collected by Petersburg。A copy of the "Treasure House of Great Wisdom" unearthed in Rajasthan, northwest bet365 offers，With a blank piece of parchment。Two thin ivory tablet documents from Burma can also be seen in the British Museum。

Of course，The most commonly used writing material in Theravada Buddhist classics is palm leaves or bay leaves，Mainly palm leaves with huge leaves，Called "fan leaf sugar palm" or "bay leaf palm" (also known as "betolo tree")，After drying、boil or soak、Let dry again，Polish with stone or shell，Finally cut into appropriate size and made，With a reed pen (to reed、Bamboo or wood sharpened into a pen) dipped in ink for writing。These traces of human processing have been confirmed in the Bayeux manuscripts unearthed in Nepal and West bet365 offers，However, the Bayeux scrolls from South bet365 offers probably were not carefully processed or cut。The origin of these bay leaves is in the Deccan Plateau，But due to large-scale use, it spread throughout bet365 offers，Can even be seen in Punjab。In South bet365 offers，Palm leaves are still used to write official and private letters，Even used in local schools。Palm leaves are also used in schools in Bangladesh，There are also students who use lamp ash to write on banana leaves or sal leaves。

The earliest ink used in bet365 offers was ground charcoal，With water、Gum、Sugar, etc. mixed，Used to make black pigment or eye ointment。About 4th century BC，Indians began to use this ink on birch bark、Cotton、Written on Bayeux and other materials。Inscriptions written in ink can still be seen in the Ajanta Caves, which were excavated in the 2nd century BC。In the chalk、Beyond Talc，Lead or cinnabar is also used as an alternative to ink for writing，Commonly found in Jain manuscripts and Brahmanical Purana manuscripts。Another example，Various types of stones such as basalt、Sandstone、Crystal, etc.，Used to inscribe decrees、Treaty、Letter、Fiefdom and other documents or poetry and other literary works。Bricks with letters or words engraved on them，Can be found everywhere in bet365 offers and Myanmar。

In addition，There are also gold plates、Silver Plate、Copper Plate、Writing media made of metal materials such as tin plates。Precious metals are rare，Mostly used to engrave royal letters、Motto or fiefdom document。Copper plates or bronze medals were the favorite way of inscribing documents such as fiefdoms and other documents favored by many kings in ancient bet365 offers，It is even used to preserve literary works。Production of copper plates，Casted from the existing sand mold (use an iron needle or wooden pen to write on the sand mold，Therefore the inscription is in the form of relief)，It is also carved with a hammer (some copper plates still have hammer marks)。Copper plate casters often imitate the form of the original，If the text was originally written on the bay leaf，The copper plate is as slender as the shape of a bay leaf，And if the text was originally written on birch bark，The copper plate is wider，Nearly square。The copper plate inscriptions in South bet365 offers are mostly in the first type of bay leaf shape，Except for Vijayanagara City (translated as "Victory City"), the copper plates of the Yadava Dynasty are in the form of stone tablets。The copper plate inscriptions in North bet365 offers are mostly in the second type of birch bark shape，Except the bronze medal unearthed from Taxila is in the shape of a bay leaf。

Just as different fonts correspond to different regions and eras，Different materials、The writing carrier of form，Also corresponds to different regions and eras。Comprehensive arrangement bet365 offers texts and Indian paleography、Ancient History、Historical Archeology、Historical Geography，Even paleoecology、Environmental Science、Bio、Chemistry、Combined research on smelting technology and other areas，It can help us understand the historical context of the development bet365 offers texts more systematically，Thus forming a deeper historical understanding of its evolution。
