The Guru left his body after bidding goodbye to his disciples and other followers. His favourite cow also died at the same instant, then the rest of the cows miraculously disappeared within a few days. There are also accounts of cows emptying their milk by themselves every day at the same time, at the place where the Guru died. He had done many miracles during his lifetime. Once he asked Rolpali cowherds not to take the cattles in a particular area for grazing warning them of a huge landslide in that area. But they refused and were swept by the landslide.

He managed to teach vedic scriptures and other religious scriptures to the children's. They may perform vedic worshipping in the temple after study. But, doing this is not a compulsion after study.
