Calligraphy since ages has been evolving from its original form. So have its functions. But the basic requirements of calligraphy have always remained there and are mutually dependent. Calligraphy is incomplete without these essentials, i.e., the tool, the medium and the surface. Calligraphy since ancient times has remained as a medium of visual communication, communicates a message(s) for the sake of wisdom, and has not widened much. But there have been a lot of experiments, reformations, and cross-cultural adaptations over the scripts of calligraphy, like writing the Devanagari script with a Japanese round brush, modifying steel tools to be ergonomic for Devanagari, installing a reservoir for ink in the tool itself, etc., which have contributed to shaping a new dimension of calligraphy. The process of evolution of letter forms has deep spiritual roots. Akshar is an experience of a very highly profound meditation process. Calligraphy can be called a process in which your mind and body are involved towards attaining a simple goal, of akshar. Akshar means the one that will remain forever.
