India's former president Abdul Kalam called for the country to be a corruption-free, developed nation by 2020 as he said his farewell to the nation last month.
The shaggy-locked missile scientist was formally replaced on July 25 by Pratibha Patil, who was elected India's first woman president late last month.
Kalam said he wanted India to become a nation "where the governance is responsive, transparent and corruption free; a nation that is one of the best places to live and is proud of its leadership."
Corruption is rife in Indian politics and bureaucracy.
"I will always be with you, dear citizens, in the great mission of making India a developed nation before 2020," Kalam said.
Kalam, who became a national hero after overseeing successful tests in 1998 that turned India into a nuclear power, had been nominated to the office by the previous Hindu nationalist government.
His bid for a second five-year term was rejected by the ruling Congress party which, political analysts say, wanted a party loyalist.
The son of an illiterate Muslim boatman, he was known for his simple lifestyle despite occupying the opulent 340-room sandstone palace that housed the viceroy when Britain ruled the subcontinent.
Kalam, who was dubbed the "People's President" for his populist style in which he reached out to young people, said he would leave the palace with just "two small suitcases" and return to teaching at a university in Tamil Nadu after leaving the post.
He noted that India had 540 million people below the age of 25 "which I consider the most powerful resource on the earth" to achieve its development goals.
A developed nation is a country that has reached a point of economic development or higher national income. The UN does not set a specific standard when dividing developed and developing countries, but most lists of developed countries would include Australia, Canada, Japan, New Zealand, the US, Western European countries and the East Asian Tigers (Hong Kong, Singapore, South Korea and Taiwan).
Other countries are called "developing nations" since they are on the road to development.
「已開發國家」(developed nation) 指已到達一定的經濟發展，或國民所得較高的國家。聯合國未設定明確標準來區分已開發和開發中國家，但一般認為已開發國家包括：澳洲、加拿大、日本、紐西蘭、美國、西歐各國和亞洲四小龍（香港、新加坡、南韓、台灣）。
