Most nights I sit in bed and meditate for up to 45 minutes. I see the thoughts fade to the background of consciousness. Then I drift off somewhere for the sit's duration. Some nights, too tired to sit up I prop pillows to elevate my head, start the chime, and begin to meditate, and eventually drift into a calm deep sleep. I trust that the beginning chime and the ending chime marking the usual period of time I sit, have become a signal, even though I am sleeping for the last chime, that I have integrated whatever is necessary to continue the process. No forcing, just allowing what is needed to move forward. Gentle, sweet. Grateful for the Dharma.
