Meditation teachers often speak of the importance to bring your practice into your daily life. For example, finding stillness and spaciousness during daily tasks and observing your emotions and thoughts throughout the day and especially during turbulent moments.
With writing, I’ve found that it’s essential to find stillness first. You have to switch off (or at least journal your way through) the mental chatter before you can get some writing done. If you don’t, the noise seeps in after every sentence, or sometimes after every word.
In addition to finding stillness you have to surrender. This can be hard to do, but when things don’t flow you really have no choice. And there is comfort in surrender. Knowing that the words might not flow today, but you’re showing up anyway. Feeling emotionally off but giving your best in spite of that. Or just knowing that you can put aside that circular thought, and just write for a while, listen to something different than your own mental chatter. With writing, some days are good, some are uncomfortable, but the practice becomes accepting whatever is and surrendering to it.
