He said Paswan used his waist belt to beat him and threatened to kill him if he did not stop his activities in Bodh Gaya.
Brahmachari told IANS on phone that it was the third time he was attacked in Bodh Gaya.
"My life is under threat and my security issue must be taken seriously. Paswan is a hard core criminal. A big conspiracy is on to kill me in Bodh Gaya since 2006 because I am exposing issues like the wrong deeds of NGOs and a branch being cut off from the Bodhi tree," he said.
"I will continue to fight corruption at Bodh Gaya," he said.
"They want to eliminate me to stop my fight against corruption at the Bodh Gaya temple," he added.
Brahmachari had written to the president, the prime minister and the National Human Rights Commission (NHRC), drawing attention to the "corruption" at Bodh Gaya, considered sacred to millions the world over.
The Bodhi tree behind the Mahabodhi temple, said to have grown from the original banyan tree under which Lord Buddha attained enlightenment about 2,550 years ago, sprouted new leaves after four years last year.
An official of the Mahabodhi temple, which the UN has declared a World Heritage site, said the Bodhi tree is the sixth regeneration of the original banyan tree.
