Pen Tree

Information – The Kalam Tree, or Pen Tree, in Vidyanagar, is believed to have miraculously sprouted when Lord Caitanya planted a pen in the ground during His student years. These unique trees do not belong to any known botanical species, despite extensive research by scientists from Kolkata. They remain a mystery and are revered as transcendental manifestations linked to Lord Caitanya’s divine pastimes.
(Author’s Note: We have not found any scriptural references for this particular pastime.)

Information – Lord Caitanya got a pen made from one of these trees. He put the pen on a tree manifest. He also made a pen again. They say that these trees are here but I did not check it, you can check on Google. It is nowhere else in the world. You can check it out and see whether it is true or not.
