Scent is a great way to orient yourself to a particular task. Incense makes that easy to do. It's a common practice to use incense before meditation. If you light the same scent of incense every time before you start, you will begin to find that you will achieve a meditative, contemplative head space faster than without it. We tend associate certain scents with certain things. You can train your brain to associate a scent with a particular activity, such as meditation. Wouldn't it be nice to get into that space more quickly so that you can get more out of the limited time you have?
Hmmm, I think I should find a scent to help me when preparing to write in my blog! What are some of your favorite scents?
