Days of Solitude and Rest

This quote of Dallas Willard, from his book Renovation of the Heart, beautifully articulates the opportunity we all have right now in this time of staying put and spending more time alone:

"The Christian philosopher and scientist Blaise Pascal commented, 'I have discovered that all the unhappiness of men arises from one single fact, that they cannot stay quietly in their own chamber.' This remark, though somewhat of an exaggeration, contains a deep insight. The capacity to simply be, to rest, would remove one from most of the striving that leads to misery. This is a capacity that comes to fullness only when it reaches our body. Peace is a condition of the body, and until it has enveloped our body it has not enveloped us. Peace comes to our body when it is at home in the rightness and power of God. 
Sabbath fulfilled in human life is really celebration of God. Sabbath is inseparable from worship, and, indeed, genuine worship is Sabbath. As the fourth commandment, Sabbath is the fulfillment in practice of the first three (commandments). When we come to the place where we can joyously 'do no work' it will be because God is so exalted in our minds and bodies that we can trust him with our life and our world and can take our hands off of them.
Now, for most of us Sabbath is first to be achieved in the practice of solitude and silence. These must be carefully sought, cultivated, and dwelt in. When they become established in our soul and our body, they can be practiced in company with others. But the body must be weaned away from its tendencies to always take control, to run the world, to achieve and produce, to attain gratification. These are its habitual tendencies learned in a fallen world. Progress in the opposite direction can only be made in solitude and silence, for they 'take our hands off our world' as nothing else does. And that is the meaning of Sabbath. 
Rest is one primary mark of the condition of Sabbath in the body, as unrest is a primary mark of its absence. So if we really intend to submit our bodies as living sacrifices to God, our first step well might be to start getting enough sleep. Sleep is a good first use of solitude and silence. It is also a good indicator of how thoroughly we trust in God. 
The psalmist, who knew danger and uncertainty well, also slept well: 'I lay down and slept; I awoke, for the LORD sustains me' (3:5-6), he said, and 'In peace I will both lie down and sleep, for Thou alone, O LORD, dost make me to dwell in safety' (4:8)."
