I have a friend, a fellow yoga teacher, who always says, “yoga is medicine”. But when you are sick the last thing you want is to choke down some cherry or grape flavored spoon full of elixir; and yet just as your mother knew best and forced it down your throat when you needed it most, I am here to tell you that when you don't feel like going to yoga class is when you need it most and even if you feel like you are forcing it down, it will make you feel better.
It is hard to imagine that breathing in, breathing out, bending, twisting, folding, breathing some more, holding chair pose, hows your breathing?, oh my god are we still holding chair?, keep breathing, don't bite your lip!, really! we are still holding chair!?, don't forget to breathe, and Thank GOD! he finally said forward fold... inhale... exhale... could be medicine, but like my favorite yoga teacher says (usually right before asking me to do some Cirque de Sole pose) “imagine the possibilities”. Imagine if you could let all that was bothering you before class roll off of you like sweat on to your mat. Imagine if you could feel the sensation of the burning in your thighs and without making a judgment about it just be. Imagine if you could let go of all that you think you can or can't do and come into crow without fear. And if you could do all of that for the 90 minutes that you spend on your mat, imagine what that could mean for your life when you step off of it.
So, go take your medicine!
