Ask, “Don’t you get sore sitting in one position for so long?”
Of course you do! The point of meditation is not to feel perfectly happy folded onto a zafu cushion…it’s to recognize when you feel stiff or sore and notice it before letting it go. Unpleasant situations arise in life all the time and you can’t do anything about them, so meditation is good practice for being able to deal with problems without freaking out and believing your legs are going to fall off.
Also, little-known fact, Buddha actually said there are four positions to meditate in, and each one should be practiced as much as the others: sitting, standing, walking, and lying down. So if you get sore from sitting…try walking for a change!
