Do you like to stay up late at night, thinking that you can make up for the loss of sleep next day by waking up late or taking a nap?
From the perspective of the yin-yang theory, it is a wishful thinking.
Remember that you are part of the universe — and cannot afford to stay out of step with its rhythm. Between day and night, day is yang and night is yin. When day moves into night, the yang energy is gradually depleted. By around midnight from 11 pm to 1 am, the yang energy is totally gone and the energy in the universe around you is fully yin.
When the yang energy is depleted, the law of nature requires that it to be recovered. Otherwise coolness will turn into ice and we will all be in big trouble. The universe would also take the state of total yin turning into yang to do ‘maintenance’. Your sleep is deep and in your body your internal organs are taking turns to do the ‘maintenance’ and rejuvenate. For example, from 11 pm to 1 am, liver is working hard to assimilate the increasing yang energy.
You cannot do these when you are awake and full of yang energy. Since you are out of step, you miss the opportunity to do something by leveraging on the power of the universe.
Even if you make up for the loss of sleep later in term of the amount of time, the quality of sleep would be rather different. It is not as deep and you body would not regain its vitality in the manner the universe awakes. You are like a nut in an engine that goes against the momentum. Sooner or later you body is going to be in trouble if the same pattern remains.
Unless it is of no choice, don’t trade the synchronisation with yin-yang for staying up late.
Sleep when the universe sleeps, and awakes along with its rejuvenation. The opportunities, if missed, cannot be replaced.
All things carry yin and embrace yang.
They reach harmony by blending with the vital breath.
