The Mitzvah to Mourn
- There is a major dispute if aveilut is deoritta or derabbanan. The consensus is that it is derabbanan. 
- An important aspect of mourning is doing teshuva. Anyone who doesn't mourner like chazal instructed is considered cruel.
- It is improper to mourn a deceased one more than chazal instructed. However, for a talmid chacham it is permitted but still it is only permitted to cry over the death until 30 days and give eulogies until 12 months. 
Beginning of Aveilut
- A person would have to mourn based on a source from one witness, even if it is secondhand, or even a non-Jew if he is speaking casually.
- The geonim hold that the first day is deoritta, while the Tosfot hold that aveilut is completely derabbanan. Shulchan Aruch 398:1 holds that it is deoritta but the minhag cited in Shulchan Aruch 399:13 holds that it is derabbanan. Shach 398:2 writes that we hold it is derabbanan.
- Rambam (Avel 13:12), Shulchan Aruch 394:6. See Birkei Yosef 395 who writes that it is inappropriate if a person doesn't cry even one tear during the first three days after the death of a relative unless he is holding back from crying because of marit ayin.
- Shulchan Aruch 394:1-2
- Shulchan Aruch YD 397:1
