Begin sitting comfortably and follow a slow breath for 5 minutes. Then bring your awareness to fluid tides within your skull and brain. See if you can gain a sense of the slight expansion and contraction of your cranial bones and membranes. Sense the stretch receptors rhythmically expand and narrow between the zig-zag interlocking sutures of your cranial bones. Feel any liquid pulse within your skull and notice how the bones “breathe,” expanding and receding like the tide flowing in and then back out of a tide pool. Feel the fluctuations within your brain itself inside your cranial bones, and sense how it moves ever so slightly, bobbing like seaweed in the waves along the shore. Remain for 10-15 minutes.
You don’t have to do yoga to know that you should not “hold your breath”. Yet in order to make it through a topsy turvy time it is common for people to do just this. When we say “holding your breath” we do not simply mean not inhaling. Of course, people rarely “hold their breath” for without breath there is no life and by way of a long held breath, you might end up passed out on the carpet! It is more common for people to constrict their blood vessels, clench their nerves or tighten their sphincters in order to get by.
