We should have constructive thoughts, consoling words and compassion

Lets be in happiness and peace always. How can this happen?

We do not have happiness and peace because we are busy finding faults with others and happy at others failings. Instead we should be working on our own faults and failings.
What we see in others is a reflection of our own self. They are our prejudices and preferences.

We can be in happiness and peace if we are compassionate towards all creatures. Knowlingly causing injury is bad.

So lets spread love and happiness through compassion and be filled with joy and peace.
