Dulon was a training regimen to help Jedi Padawan learners in the art of lightsaber combat. This training involved solo sequences of moves in which they did not fight an actual opponent, but merely envisioned the opponent's presence. This, in combination with other lightsaber drills known as velocities, helped to prepare them for live combat by using the Force to take them beyond what would normally be physically possible.[1]
