Much goodness can comefrom prayer.
However, We often feel that it is difficult to pray three times a day. Part of our daily prayers is a supplication to G-d for the rule of righteousness and justice. This is an example of how we often feel that following Mitzvot is a strain while in reality we should not feel that way. In our Perasha the Kohanim are commanded to avoid contact with the dead. The Midrash Tanchuma says that this is similar to a king who decreed on his chef not to see a dead person.
