In his 20-minute speech, Kejriwal called the day very historic and formation of his government a "victory of the aam aadmi (common man)".
"It is not Kejriwal who took oath today but it is the common man...It is the victory of the common man," he said, adding "the road to truth is not easy but full of thorns and we will face all future challenges".
"We are not here to grab power but to give governance back in the hands of people. Now, 1.5 crore people of Delhi will run the government," he said.
Delhi has shown the country that politics can be done with honesty.
"We had lost all hope and thought that politics is hooliganism and corruption. But in Delhi Assembly elections, people have proved that politics can be done with honesty, elections can be fought and won with honesty," he said.
While appealing to people from all political parties including BJP and Congress to support them, Kejriwal referred to BJP's Harshvardhan as an honest man.
"I know Harshvardhan personally and can say that he is a good man, but I can't say about his party. I appeal to other Congress, BJP and other parties. If you feel we are going the right way, forget your parties and support us," he said.
