I was late to class. I left work late, and once I realized I was going to be late anyway, I decided to lay down for a few minutes and relax in the quiet. Then I felt naughty, so I booked it down to Chinatown, and actually wasn't as late as I expected.
But that feeling of just wanting to lay down had taken root, and that's when the struggle really started!
In class, we learned about the legend of Patanjali, and then we practiced. After practice, we did a kriya meditation, which is when you try to control the flow of prana. It was a wonderful exercise, and though I was tired after class, my mind felt at ease.
