67-year-old Ban, who described himself as a "student" of India, proudly accepted Degree of Doctor of Letters (Honoris Causa) conferred on him by the prestigious Jamia Milia Islamia here.
"For decades, I have been a student of India. Now, I finally have a degree to prove it," Ban said after receiving the honour.
Ban, who began his diplomatic career in India 40 years ago, was effusive about India and its rich tradition and culture in his 20-minute acceptance speech.
Beginning his speech on a personal note, he said his son was born in India and years later, his daugther married an Indian.
"The couple produced what I consider to be the world's finest joint venture between our two countries -- my grandson Jai," he said, evoking laughter among the audience.
"For all these reasons, I say when I am in India, I am at home," the UN chief said.
"I arrived in New Delhi exactly 40 years ago on my first diplomatic posting. It was one of the best things that happened to me," he said.
Ban said ever since that, he had got lessons from the "proud history" of India and its traditions. "I have been inspired by your example. The bonds go deeper."
