There are many different ways to cleanse and purify, or just move energy around. One of my favorites is the smoke bath. This is where you burn an incense that has the property you want or need in any given moment and consciously receive it into different areas of your body, as though you are inhaling it with that part of your body.
The Heart Math Institute has some great videos on YouTube about how to do heart based breathing. I really appreciate the work that they are doing. You are welcome to give that a try or do something different that's more appropriate for you.
There was a period of time, a few years ago, where I was doing a lot of smoke baths, on an almost weekly basis. (I tend to have a lot of energy to move around, Tower card lady that I am!). I'd cut back in the last couple years but have recently revived the practice in my home at a prompting from Spirit.
As you stand and receive the smoke, allow your focus to move over the entirety of your body, both internally and externally. If there are any areas that continue to feel stuck or stagnant, remain there for a while longer. If there are any areas that you feel blank or numb, that can be an indication of a spot in need of some additional focus.
It's simultaneously a very simple and complex practice because the majority of the working takes place internally.
* basic and obvious note- use sense and safety when doing any working that involves flame. Be conscientious when doing this, as we should all be anyway when doing the work of living a conscious life.
