Chasidut על אבות 5:3

However, each and every person must come into trial – even if he receives God’s Godliness into his thoughts as we have explained above – nevertheless each person is tested with ten trials, as they said about Abraham, “Abraham was tested with ten trials and withstood them all” (Mishnah, Avot 5:3). And the trial is that they strip him of the Connection with which he was connected to Blessed God through Awareness. At the moment when he comes into the trial, only Free Will remains with him; for without this it would not be called a trial. For certainly through the Connection the tzaddik holds his path (Job 17:9), and in this way his Awareness is diminished – though not completely removed – and if he withstands the trial, it is because it was already fixed in his heart from before when he had expansive Awareness.
