Shri Bethakjies are the places, where either Shri Mahaprabhuji or any one of the members of his dynasty had stayed and recited Vedas or Gita or any Puranas like Ramayana.
Shri Mahaprabhuji started His pilgrimage (Yatra) of Bharat, at the age of 11 years, as you are aware that He always walked barefoot. He walked extensively, from Badrinath to Himalayas, Rameshwar in South, Jagannath Puri in the East and Dwarka in the West. He accomplished this thrice in his lifetime, on barefoot with certain vows. During the time between these pilgrimage (Yatra), He usually preferred to camp out in the open. He used to choose a place which was close to a river or lake, and He would rest under a tree, so as you can see, He loved nature and a peaceful environment. Now, in many of these places, He used to read the “Bhagvat”, as a “Parayan”. This would take at least 3 to 7 days. In many places He had also read Valmiki’s “Ramayan”, and the holy “Geeta”. This reading of religious books before an audience or alone within a limited period is called “Parayan”. Shri Mahaprabhuji stayed for longer periods at most of these places and did “Parayan”. It is the place, the particular spot, where he did “Parayan”, is called “Baithak”.
