To have a calm and joyful life, the religion taught us many techniques
Not only did religion provide some programs for us to have a calm life, but also it persisted in it. This calmness has various aspects: physical, mental, personal, social, vocational, and non-vocational. It also includes the ways to eat, wear clothes, have private affairs among the married ones, sleep calmly, relationships with neighbors and friends.
On the whole, if you want to figure out whether you are close to God or not, you can see whether you are calm or not!
