He also said a comprehensive programme to teach yoga in state schools would be drawn up soon.
"Yoga is not a religious ritual. There should not be any misunderstanding that it is part of any religion. Yoga should be practised with a free and secular mindset," the CPI (M) leader said.
The chief minister also said yoga should be seen as a set of exercises that can be practised by anyone.
"There has been a conscious attempt to create misunderstanding about yoga. Any move to connect yoga with any particular religion should be checked," Vijayan said.
