It was Sardar Vallabhbhai Patel, Thathachariar says, who regretted the lack of unity among the religious sects and this prompted the Kanchi Sankaracharya to take the initiative in bringing the heads of different Mutts together into a single organisational frame (when the Constituent Assembly was in session) so that they could speak in one voice.

In the event, thanks to such concerted effort and support by sections across the country, the Constitutional guarantee of religious freedom became a reality.

I did not know about this aspect of Patel‘s contribution. In the event there was no representation, what were the constitutionalists planning to do? Not mention religious freedom at all? It would be interesting to see the records of discussion on this issue at the constituent assembly. May be Ram Guha will discuss this aspect too in his forthcoming  Indian history book!
