Hazare, who was facing allegations that he was moving towards RSS aided by Ramdev, said he went to the meeting on September 19 following a message from the yoga guru.
"During the meeting, Ramdev suggested that we tour together. I did not give any assurance. I will do it only if I am convinced that he is not backed by any political party. I am not clear about it," he told reporters.
"Once it is clear that Ramdev has no political backing, then I will think about joining him," Hazare said.
In a blog last week, the veteran activist had decried efforts to link him with some parties and "communal" outfits, in an apparent reference to allegations that he is closing ranks with RSS through Ramdev to run the anti-corruption movement after the split with the Arvind Kejriwal-led group.
