The Trial of Insight was the last test offered as part of the Trials of Knighthood. Installed in the Trials program after noting that, while a Jedi could take down a Sith, they could be undone by common thieves, this test helped a Jedi to see what was really in front of their eyes through use of the Force. Seeing through illusion, evaluating an individual's true persona, and unveiling lies are essential to a successful mission. To complete the test, Padawans were forbidden from reviewing any of the possible puzzles in the Jedi Archives; such an advantage would make the test moot. The Trial might require a Padawan to analyze and decipher the High Riddles of Dwartii, or decode broken text in scattered files. Sometimes, a field of stones would be laid out on the Trials Chamber floor and a Padawan would be forced to locate the single grain of sand amongst it.
