Sripad Bhaktivedanta Sadhu Maharaj travels all over South America preaching the glories of Sri Chaitanya Mahaprabhu. Maharaj is the grandson of Sri Raghunandan Prasad Singh,the King of Mungir who converted to Gaudiya Vaisnavism and who build several temples in Vrindavan and in Mungir. His grandson continues the service in the temples of his ancestors and also recently entered into the renounced order of life. Since he met with Srila A. C. Bhaktivedanta Swami Prabhupada, who told him many years ago to serve the deities with his own hands and to preach, he had prepared himself for this task to follow in the footsteps of the great servants of the supreme Lord and to preach to all suffering souls.

His first tour to South America took him to over 40 temples of different Vaisnava missions and he inspired hundreds of souls to make commitments with the Vaisnava principles of life. In Kartik he will take over 40 devotees to Mungir, Bihar to continue his spiritual life mission there.

He also helps to organize the Vaisnava Academy in Mungir Mandir, Vrindavan Mathura Road.
