Rekpa De

Rekpa De was a male Jedi Master when Yoda was still a Jedi Knight (around 850 BBY). He may have been a Twi'lek. Rekpa De taught basic lightsaber skills to young Padawans in the Jedi Temple. His best known aphorism was:

"Do not see a lightsaber duel as a choice between winning and losing. Every duel can have many, many outcomes. When you concentrate solely on winning - in lightsaber duels as in everything else - you sully your victory. Winning becomes worse than losing. It is better to lose well than to win badly. And it is always better to end a duel peacefully than to win or lose."
