Who arranges the necessary materials or Samagri in Varanasi?

Typically, the pandit or puja service you book in Varanasi, especially those operating at Pishach Mochan, will arrange for all the required puja materials (Samagri). This includes items like flour, rice, sesame seeds, flowers, fruits, incense, sacred threads, etc. The cost is usually bundled into the overall puja package.
