"Why did she cry?... she understands that the power many people seek is poison...She can see it because of what it does to the people, and the people around, and most important, she is not attached to it (power)," said Gandhi.
"We should not chase power for the attributes of power, we should only use it to empower the voiceless," he added, amid thundering applause of over 1,500 delegates inside the 1,300-capacity Birla Auditorium.
Gandhi then talked about "hope" and how after the assassination of his grandmother and prime minister Indira Gandhi, the family was left shattered.
He said he used to play badminton at his grandmother's house with two of her security guards who were "friends", and that the sport gave him "balance in a complicated world".
"I was taught the game by two policemen who protected my grandmother, and who killed her, destroying that balance," said Gandhi as the crowd listened in rapt attention.
