Being holy is about being good and kind and being holy is about being obedient and thankful to G-d. Now back to my first portion. It talks about getting close to G-d. The Cohen Gadol, the High Priest had a once a year chance to go to the holiest place in the world, the Holy of Holies in Jerusalem. The High Priest had to bring many different sacrifices, and perform many rituals.
Some people sit around and meditate all day.
Some jump up and down a lot. Some sing songs. However, our second portion today, Kedoshim, tells us how to get close to G-d. The reason these two portions are attached is that both portions tell us how we can get close to G-d. We can get close to G-d with prayer and sacrifice.
