Book of Practical Lightsaber Technique
published by Novacron Press (book listing 162.S*D/3/r^6.56), this tome was written by the Jedi Master Vo'ren Faalo. Faalo had developed a series of practice routines that sharpened a Jedi's control of the Force while wielding a lightsaber. Faalo described a series of cadences in which the student used steel ball bearing set atop candles. The student had to cleave the steel balls in half without melting the candles. The cadences ranged from a single steel ball and candle to hundreds, and required intense concentration.
