Buddhist texts were initially passed on orally by monks, but were later written down and composed as manuscripts in various Indo-Aryan languages which were then translated into other local languages as Buddhism spread. They can be categorized in a number of ways. The Western terms "scripture" and "canonical" are applied to Buddhism in inconsistent ways by Western scholars: for example, one authority refers to "scriptures and other canonical texts", while another says that scriptures can be categorized into canonical, commentarial and pseudo-canonical. Buddhist traditions have generally divided these texts with their own categories and divisions, such as that between buddhavacana "word of the Buddha," many of which are known as "sutras," and other texts, such as shastras (treatises) or Abhidharma.
These religious texts were written in many different languages and scripts but memorizing, reciting and copying the texts were of high value. Even after the development of printing, Buddhists preferred to keep to their original practices with these texts.
