I am looking for a PDF version of Sampradāya Kalpadruma  of Viṭhṭhaleśa.

Would be much obliged if anyone could share a copy of it. 

Further, are they any scholars here who have researched further into the thesis that Jagannātha Paṇḍita was a descendant of Vallabhācārya from his mother’s side? I am aware of R B Athavale's work regarding this.

However, I have no further reference which establishes this firmly, and pointers to any research papers on this would be helpful.

How does the  Puṣṭimārga tradition look at this thesis? Is it a widely held belief in the tradition?

Kind regards,

Santosh Gokhale
