This lineage is the Path of Radha.
Purna Das Baul first recorded this in the 1960's Hindustan Records. It has already been recorded and preserved by this family of Baul.
What Nabani Das is saying, my translation into English with the help of Babu Kishan
Love is like that out of site out of mind, you must constantly remember your beloved.
Braj is where the pastime of Krishna and Radha take place the memories of her play with her love Krishna.
The path of Radha.
I have added these Vaishnava Baul practices from this lineage here because it will help one understand that there is a deeper practice of Love for the Bauls in following the path of Radha. This is very simplistic and there is much more involved.
Sri Nabani Das Khyapa Baul gave the name Ananda Lahari to the Baul Mystic drum called the Gugubi or Khamak.
