All happiness or unhappiness solely depends upon the quality of the object to which we are attached by love.
Happiness doesn't depend on any external conditions, it is governed by our mental attitude.
I do believe that if you haven't learnt about sadness, you cannot appreciate happiness.
HAPPINESS, BELIEVE THAT IF YOU HAVEN'T LEARN ABOUT SADNESS
Everyone chases after happiness, not noticing that happiness is right at their heels.
Happiness is beneficial for the body, but it is grief that develops the powers of the mind.
HAPPINESS, GRIEF THAT DEVELOPS THE POWER OF THE MIND
The word 'happiness' would lose its meaning if it were not balanced by sadness.
HAPPINESS, BALANCED BY SADNESS
