All yoga practices are a cleansing of sorts - releasing stiffness from the body, releasing the mind from cycling thoughts. There are several Kriyas with a capital K in tantric yoga; these are often intense practices for cleansing the areas most congested, one of the most common is simply using the neti pot.
Through repetition, all of our asanas become kriyas. Consider this next time you practice. Move in and out of your postures with your breath multiple times feeling how this affects your body and beyond. Practicing in this way (much like we do in Slow Flow Yoga) shows us absolutely how our physical practice affects the metaphysical. Its an internal housecleaning that changes the atmosphere around and within you, bringing harmony to even contradictory aspects of yourself as you come closer to your own truth.
May the truth set you free!
