One can appreciate the beauty of the pre-dawn two ways: staying up through the night or waking up early. I almost never stay up through the night, but find myself waking up in the pre-dawn hours frequently lately, especially when we have not been getting any rain, and the rain finally arrives in the wee hours.
Classical yogis advise that the early morning hours are optimal for practicing. I have been choosing, when I awake in the very early morning, to go into my studio and practice, rather than struggling to get back to sleep.
I find that I am less tired and more productive if I take this invitation to practice rather than worrying about sleep deprivation and struggling to rest.
