The feelings one should feel
- One should be pained over the destruction of the Temple. [1]
How should it be said?
- It is the practice to say Tikkun Chatzot while sitting on the floor near the doorpost witth the mezuzah. One shouldn't sit directly on the ground rather one should sit on a cloth, pillow or small bench. If the floor is tiled one can be lenient to sit directly on the floor. [2]
- The Minhag is to place ashes on one's head in the area where the Tefilin Shel Rosh is placed. [3]
- Another practice is to not to wear shoes during Tikkun Chatzot. [4]
Timing
- Ashkenazim hold that it should be said right before Chatzot and then one should learn from Chatzot until morning when one can pray. [5] However, Sephardim hold that it should be said at Chatzot of night or afterwards until Olot HaShachar. [6]
