Happiness and harmony are mental states, or states of mind.
They are not bestowed upon you by the environment, or even the people around you.
Of course those things play a role in your life, but, no one walks up to you on the street and hands you happiness.
It’s up to you to achieve that state. How you accept and frame the world around you is a big part of that.
If you’re not happy with the world outside of you, the place to look is the world inside of you, because one is simply a reflection of the other.
