Wake naturally. That means any time (of the day). Sometimes I have this kind of luxury, when the day begins at mid-morning and ends well past midnight. Night time seems to have a calming effect on me. It induces my mind to focus and be productive.
My sister-in-law said after she wakes she must get out of bed, otherwise she’ll get a headache. But I find the time when the mind begins to wake to be a magical moment. Memories, emotions and new thoughts reemerge together. Feelings come back, and sometimes with a line or two, or maybe a little tune. They don’t ask to be written down; and if I reach for a pen I disturb the delicate veil between consciousness and sleep and the magic is gone. To savor and listen and feel–although I don’t know anything about meditation, I suppose this may come close to some aspects of it.
