I do not consciously choose to go to sleep.
Sleep is an unconscious choice.
It is the experience of losing consciousness.
I can consciously choose to stay awake, for a limited period, but I cannot choose to go to sleep.
Sleep is an unconscious choice that has my conscious agreement.
Sleeplessness is also an unconscious choice.
Sleep requires the agreement of all the unconscious aspects of my Self.
My sub-conscious Self chooses sleeplessness when it is too busy processing a problem.
When I am challenged by my problems, I may sleep less than I consciously choose to.
My super-conscious Self chooses sleeplessness when it has important revelations for me.
Whilst either my sub-conscious or super-conscious mind remains active, sleep is not a conscious option.
All three aspects of my mind are required to be in agreement for sleep to effortlessly occur.
A sleepless night is not an option when all three minds are in balance, equanimity and inner peace.
