Sri Caitanya Mahaprabhu and all the teachers in His line want us to be happy. Everyone wants to be happy, but generally we can only find a very little happiness and affection in this world, and even then it is mixed with sorrows and suffering. Why is it that we are unhappy, even though we have so many possessions? We should consider this. Napoleon was not a street beggar, and neither was President Kennedy. Princess Diana was also not a street beggar; she was not at all ugly, foolish, or ignorant. On the contrary, she had name, fame, beauty and everything one could desire, and she was married to Charles, but she was still not happy. Why is it that even people who seem to have everything are unhappy, in spite of their wealth and opulence? We should think about this very seriously.
