There is a space in yoga and meditation referred to as the midline.
For yoga postures this is often referred to as hugging the midline or being in alignment.
In meditation, you feel your sit bones on the chair or the ground (or cushion); you gently rise up with relaxed shoulders and jaw and face muscles breathing normally feeling your center.
Your heart is at the center of your central energy channel, the sushumna (see below).
How do you keep aligned with or coming from your center or your heart with your words and actions?
We practice yoga and meditation to be able to find this space again and again, on or off the yoga mat or meditation cushion.
We practice to find this space and to become increasingly anchored in it so it is where we come from more and more often in our daily lives with our family and friends, at work, and in all our endeavors. It becomes a source of strength during difficult times.
