"I am very sad to learn of the sudden death of our former president A.P.J. Abdul Kalam yesterday (Monday) evening. This is an irreparable loss. He was not only a great scientist, educationist and statesman, but also above all a real gentleman," the Nobel Peace Laureate said in a statement.
He recalled that over the years he had the opportunity to meet and interact with him on many occasions and always admired his down-to-earth simplicity and humility.
"I used to enjoy our discussions on a wide range of subjects of common interest, but mainly concerned with science, spirituality and education," the elderly Buddhist monk said.
"I offer my condolences and prayers to his family and the people of India at this sad time," he added.
The Dalai Lama has lived in India since fleeing his homeland in 1959. The Tibetan administration-in-exile is based in this northern hill town.
