Sorry for not being clear. Thanks for explaining HaLeivi.
Basically, i’m talking about the point that when you do something on the outside it makes you feel that way on the inside. It works with everything, for example, if you want to become a calm person, than a way to achieve that is by PRETENDING to be calm on the outside, and than it will soon come on the inside too. Soon the person will be a calm(er) person for REAL.
It’s the same thing here. By actually doing an act you make it become part of you. Look above for the ideas of some acts. Good luck!
