SEATTLE (Reuters) I don’t pretend to have reached enlightenment. Yet, with all the chaos going on in financial markets, we clearly need yoga more than ever. Here are 10 tips for being mannerly on your mat:1. On arriving late (or leaving early): The main thing here is, try not to do either. However, stuff happens, and the best-laid plans of mice, men, and yogis often go awry. In some private studios the door will be closed and quite possibly locked, thus taking care of what to do about late-comers. Pounding on the door would not be a viable option here. In gym settings, or in studios where walking in late is possible, be respectful of the meditative yearnings of the rest of the class who showed up on time open and close the door quietly, tiptoe in, open and lay down your mat as delicately as if you were handling TNT. Better yet, if the class opening meditation is underway, wait until it is finished before making your late entry; in that case, quietly apologise, at least by silently mouthing “sorry” to the teacher. Be as unobtrusive as a pickpocket. And if you must leave early, best to inform the teacher before class starts, and leave with the utmost quietness. Getting up during savasana is a no-no.2. Avoid wedging your mat in where there is insufficient space Your teacher can help rearrange the layout of mats. That way you won’t have to incur the wrath (wrath is unyoga-like, yet not uncommon in such situations) of participants who are already deep into their own inner as well as outer space.3. Do not tread on others’ mats This should go without saying, but I am saying it anyway because I see it happening all the time. If you can do Warrior poses, you can step over a mat!4. Come to class clean Body odor is a big distraction. If your routine is to work out vigorously and then come to yoga class, wash off the sweat and use a deodorant. Hand sanitisers should be liberally employed. Offer to share with your neighbours, especially in flu season.5. Avoid perfumes and colognes Many people are sensitive to fragrances.6. Wear clothing that is appropriate Yoga is not about fashion statements. Comfort and practicality rule. Please, leave your shirt on. I have on two occasions witnessed practitioners strip during class. I suppose that one may ask permission before doing so in an unusually warm setting. No apologies to Bikram.7. On doing your own thing: Don’t. Even if you have a better practice than the teacher, or anyone else in the room. This kind of thing leads to a free-for-all, which is definitely not conducive to a mind-body-spirit balanced class. If there is a pose that you just have to do, and the teacher is not offering it, wait until the end of class and go do it to your heart’s content.Now, if you are pregnant, that is a whole other matter. You do need to modify poses and avoid certain ones as well. Best to declare your condition to the teacher before or at the beginning of class. Otherwise your twisting to the opposite side and avoiding Cobra and Locust poses, among others, may confuse your neighbours.8. Breathing too loud Uijayi pranayam (ocean-sounding, or victorious breath) is a wonderful practice, even if you have not been invited by the teacher to use it. However, it can be distracting to others. It was never meant to be heard from coast to coast, or even across the room. Properly performed, it should be audible only as far as the next mat over. And please, no grunting; if the pose is too strenuous for you, simply back off and pause in Prayer or Child pose.9. Thank your teacher Simply repeat Namaste after she says it at the end of class, even if you are a bit unsure of exactly what it means. And perhaps you might take a moment to expand upon the sentiment by saying a bit more about how great the class was, etc. Teachers love to get feedback.10. Clean up That means wiping off your mat, especially if you are using one that belongs to the facility. Put away your props, too-- neatly. Be like a Boy Scout and leave the place a little better than you found it.Mary Mitchell has written several books on the subject of etiquette, including “The Complete Idiot’s Guide to Etiquette”.
