In general, people use anywhere between 2 to 5 sticks per day. It depends on how often you burn the sticks, how large the room is, and how long you wish for the scent to linger. Two sticks are sufficient for one session, but you can burn three if you wish to bathe in the scent. Moreover, if you’re burning the sticks during an ordinary ritual like praying or meditation, one incense stick is sufficient.
