My most peaceful time of day is at the end of yoga when we do our pranayama breathing meditation and shavasana. The reason for this is because the rest of my day is full of 2 year old and if it's a day like today, it's full of 2 year old that doesn't take a nap.
As I get older, I realize why people older than I (much older) like quiet. I still love music and being crazy loud sometimes, but other times it's nice to be left alone to my own thoughts.
While practicing my 3 times weekly meditation, I have discovered it is extremely hard to clear my head and not think about anything at all. I try so hard sometimes, but as expected, a thought will pop in my head and then I'm ruined. As some might know or not know, during shavasana or corps pose, you lay there unmoving, keeping your mind free from thought. It's harder than it sounds. My mind is constantly going from one thought to another during the 5 to 10 minute rest.
Long story short, as I work at clearing my mind, I find more peace and less worry. Regardless of what is going on my life. I think it's important and very helpful for me to calm my mind and have a little bit of quiet.
As a reminder to myself of how I feel now (everything always changes and I don't want to forget), it is important to take time to rest not only our body, but our mind as well. Even if it's only a few minutes a day. I feel so much less stress in life because of it. It's fabulous!
