Police said the incident took place this afternoon when the three-day cleaning drive came to an end and the ashram authorities were inspecting the work.
"The bodies have been taken out after breaking the tank and sent for post-mortem," Superintendent of Police (City) Shailesh Pandey said.
To "ensure" that the work was done to full satisfaction, the mahant, Tulsidas, asked his 35-year-old disciple Ravi to enter into the tank. When he neither came out nor responded, the 50-year-old mahant entered into the tank.
Policemen from Goverdhan police station rushed to the spot and recovered the bodies, the police officer said.
