Happiness and Sadness is inside us.

We spend lot more time at work than at home. Coworkers give us lots of reasons to be unhappy.
You come home and your weekend is spoiled sometimes. They themselves are doing lots of external things like going to a party, play golf, see a movie to be happy. But happiness and sadness is inside us.
It is our birthright to be happy. We are all souls, loving, pure, happy etc... We are all connected. It is when we come in the physical body, we look different, caste different and religion too.

Happiness and sadness is inside us. We do not need to look for happiness outside. Look within and listen to the silence within.

Maintain good feelings in the mind. Follow path and actions for the good of yourself and others.
Giving always bring happiness. Be in the company of God and remember that there is always something new happening and it is always for our benefit.

If some family member made us sad and we hold on to it , then we are trapped in the sadness. Forgive and forget to be free yourself. It will be generous of you to do that.

If we want to teach other lesson, then role model the good path. Forcing will not help.
