We’ve all seen them and smelled them - from yoga parlours to out-of-the-way parties to, for those of us who travel, in pretty much every single temple all across Asia. From sticks of varying sizes to month-long-burning circular ones and even small pyramids, each of them smelling something different - jasmine, cinnamon, spices and pretty much everything in-between. Whether you like them or not, there’s no doubting both the significance they play in buddhist and hindu ceremonies and how important they are for literally billions of people (yes, that’s more than 2 billion!).
