Hate is a joy killer. Always keep it out.
When a thought of hatred arises in our mind, replace it with thought of love, forgiveness and good will.
Fear, hatred, jealousy, envy and resentment are promoted by the mainstream media through innumerable ways. Identify them and keep them out as they only bring destruction.
Thinking and exaggerating about future misfortunes is killing all joy we have in the present.
For joy, happiness and fun to flourish the essential ingredient is love.
