The improvisation of a text happens only through its text criticism. Every new edition of a text tries to rectify any
mistakes in the previous edition. As the number of editions increases, the clarity and quality of the content advances. In the case of ancient manuscripts composed of an author and reproduced the same matter by scribes of
different specialisations or disciplines, some scribes even copied without knowing any idea of the subject dealt
with merely for payment. Hence, analysing the variants produced through copying should be considered with attention and should be critically edited to reach nearer to the original work. Their justification of the author can be
done, and the proper knowledge of the book can be assured for the scholars and readers. Textual criticism is the
only way to find the originality of a book written years ago.
