wandering mind

During our practice, often we find our thoughts floating away, trailing off, further away from the class.
Sometimes,our mind busily comparing ourselves to others, thinking "hey,why can't I do that??" or just some random thoughts that suddenly pop, like "hmm, what to cook for dinner?". (the later is actually taken from my personal experience :] ).
These thoughts preventing us from being present, reducing our self awareness, and before we know it, we're not achieving as much benefits from the class.

One easy way to bring back the focus to the practice is by paying attention to your posture, feel any sensation when you come in and out of the pose. Checking your alignment, your feet position, or your stance in standing postures are also good, but don't get too caught up with it.

Another way is by bringing the attention to the breath, especially in balancing asanas. Sometimes we unconsciously holding our breath to be steady. If you find yourself holding your breath, just gently release your breath, and start to breath smoothly again.

Next time you practice, try to catch the moment when your mind start to wander, and slowly bring it back to present.
