Why are people unhappy?

A lot of people have dull, meaningless lives, and they're unhappy. Talking to a therapist won't change that, unless it results in the person living differently. If someone will spend $75 to see a psychiatrist, instead of spending it on a party, that's not mental illness, that's stupidity! If you don't do anything, then of course you're going to be bored and depressed.

--Richard Sandier

Why are people unhappy?

Because they are conditioning their happiness with limited physical resources, they try to achieve non-physical by physical means and no matter how much they expand, still they are not happy. Once they relate our experience of life to what they have or don't have - conflict is inevitable.

--Sadhguru
