A self-proclaimed Brooklyn guru has been arrested for allegedly plying two female followers with a knock-out brew during religious ceremonies so he could rape them.

“Relax, it’s part of the ritual,” Nigel Kennedy allegedly told one woman as she awoke to him having sex with her.

Kennedy, 51, pleaded not guilty Wednesday as he was indicted on rape and other charges for the sick crimes.

The East Flatbush man formerly owned a religious-goods store in the same neighborhood, prosecutors said.
