Hazare, 74, 'is fine', an activist of India Against Corruption told IANS. 'He was fine till late yesterday, and so is the condition now I think.'
The volunteer added that a meeting of Hazare and his close aides was going on but the subject being discussed was not known.
An estimated 10,000 people were at the Ramlila ground Sunday morning, raising slogans hailing the Gandhian for insisting on an effective anti-corruption legislation.
A large number was also having breakfast provided by the organisers -- biscuits, bread pakora, patty, aloo puri, and tea.
Many poured through Hindi newspapers, also distributed for free at the site.
Hazare began his indefinite fast Aug 16 soon after his detention while he was proceeding to the J.P. Park.
The same day he was taken to Tihar Jail, where he remained until Friday when he shifted to the Ramlila ground.
