The mind dissipates a tremendous amount of energy on pursuing thought associations and reliving memories continuously. In my recent readings, I found that the Buddhist it is called the ‘chattering monkey mind’. It never stops. Themes are repeated over and over again without any solution presenting itself. I have known older people who could still become outraged by the memory of some minor incident which occurred almost half a century ago. In all this time they had never been able to put it out of their minds. To the contrary, they strengthened the incident by constantly thinking of it.
The worst is reflecting on a problem when waking up in the middle of the night. Instincts are nearer the surface then. Emotional drastic solutions present themselves. On waking up in the morning, more often than not, all nocturnal resolutions seem far away and are seldom followed.
Lesson: when waking up at night don’t give in to mental acrobatics. Relax, let awareness descend from the head into the body.
Try to contact all parts. It may lead to ‘centering’ – a harmonious blend of bodily consciousness.
