Shah Jahan waged war in Southern India and Persia and he was able to expand and consolidate the Moghul Empire considerably. He also constructed many important buildings and mosques. He even built his own city, Shahjahanabad [now Old Delhi], at Delhi.
Upon the entrance to his Hall of Private Audience in his palace, he placed a Persian inscription in letters of gold: "If there be Paradise on earth, it is this, it is this, it is this."From:Sri Chinmoy,The Moghul Emperors, Agni Press, 2001
