The characters of Rugmangada Charitham, Nala Charitham, Kottayam stories are not gods. They are worldly characters, the ancestors. The artist performing these characters on stage should identify with those human characters. In Kathakali vachikam is the recital and angikam is the sign language. These should go together. Acting should also come up with this. Should keep in mind that you are presenting a character. Then I think every body can do this.
