Bhojpatra is used for making yantras as well as writing of mantras for activating wealth in one's life. The tree is considered sacred so Hindu scriptures, mantras and verses are written on Bhojpatra. It's also used during hawan. 11 Gomti Chakra wrapped in bhojptra is kept in one's cupboard/locker to grow one's wealth and attract abundance in one's life. It's auspicious to include this leaf in your pooja rituals.
