When we understand our relationship with God then we all will be happy. It is an essential factor for establishing peace in the world.
For a person who has suitable shoes on his feet, there is no danger even when he walks on pebbles and thorns. Similarly, for one who is always self-satisfied there is no distress. Indeed, He experiences happiness everywhere.
Through the popularizing of hari-kirtana, or the sankirtana movement, the brahminical culture and ksatriya government will automatically come back, and people will be extremely happy.
Purport on Srimad Bhagavatam 7.2.11
There are many in this world, and specially in India, who think wealth & power can make a person happy. For them I say, I am comming right from that point, down the road, there is nothing!
