Guru Maharaj: I don’t know particularly about Purushottama vrata. In regard to the Damodara vrata or Catur masya, he used to criticize that the Gaudiya Matt people grew beards but they did not do any dietary restrictions. He said if they do the vrata, eating havishanna or unspiced kichri then you can grow a beard. Ha! One year we did havishanna for Srila Prabhupada. It says in the sastra what is havishanna. It says fruits, roots, wheat, rice, barley, mung dal, certain types of spinaches, raw papaya. It is interesting, it says you should not take fruits with many seeds.  Any way you can see in the Hari Bhakti Vilasa, what constitutes havishanna. Not just the khicri, it is a whole range of things.
