- For the first three days of mourning, it is a mitzvah to cry in mourning.
- During this time, one should consider that he is required to improve his ways.
- People may not greet or be greeted by a mourner. If they greet him in error, he should reply, "I am unable to return the greeting, for I am in mourning."
- The "work prohibitions" during these days apply even if the mourners will suffer financial loss.
