The best remedy for those who are afraid, lonely or unhappy is to go outside, somewhere where they can be quiet, alone with the heavens, nature and God. Because only then does one feel that all is as it should be. Anne Frank ( https://www.annefrank.org/ )

Solitude and contemplation are sisters. Close sisters. They walk hand in hand. Solitude is so much more than silence and contemplation so much more that just thinking deep thoughts.  The dictionary defines "solitude" as "being alone".  However "being alone" is very different from "loneliness" which means "our current close relationships don't meet our needs." 
.
One can be surrounded by all kinds of people, and as author and writer Gretchen Rubin observes, yet when experiencing loneliness "it can be draining, distracting, upsetting" and perhaps even destructive.  Whereas "being alone" actively desiring solitude "feels peaceful, creative and restorative".  Solitude, alone time, can also be a time for contemplation.
.
The act of Contemplation, as defined by Saint Gregory (c540 - 604) a contemplative, a missionary, reformer and physician of souls meant "learning to rest in God."
.
Thomas Traherne, an Anglican priest ( 1637-1674) whose book "Centuries of Meditations" is now considered a devotional classic and is filled to the brim with "felicity" which also means "blessedness or happiness".   Traherne's way with words has an almost rhythmic, hypnotic quality.  Its mysteriously suggestive images linger in the mind, and soothe the troubled soul.
.
That is the essence of "contemplation" thoughts that linger in the mind and soothe the troubled soul.   Traherne discovered "felicity" in his sense of the unity of all created things.   He was undeniably a Christian writer and his meditation on the cross is particularly striking.

However, Traherne views the Cross as "the abyss of wonders, the center of desires, the throne of love."  He does not dwell on the person of Christ.  For Traherne, "All things point to their Creator; everything, therefore, from the smallest grain of sand to the largest heavenly body, is clothed in glory."   The world was not, as for the Puritans, a wilderness fraught with dangers and temptations, but the "beautiful frontispiece of eternity," a theatre manifesting the wonders of God the Creator, a school offering lessons in joy, delight and felicity.
.
The love of God underlies everything that Traherne wrote.  He saw all things as created by a loving God for the pleasure of human beings, and so strong was his sense of the love of God in his own life that he sometimes wrote as if the entire universe had been created specifically just for him.  The love of God is so delightful that 'God infinitely rejoiceth in himself for being love."  God is present by love.  By love God is great and glorious.  By love God lives and feels in other persons.  By love he is pleasing to himself.  The love of God extends to all objects and creatures.

CHOOSING SOLITUDE - AN ACT OF PRAYER

As Ward Cushman points out in an interesting online essay, there are two ways we can learn from Scripture.  The first is, as you'd expect, through instruction, for example, we are told in Ephesians 4:32, "Be angry, but do not sin; do not let the sun go down on your anger."  
.
The second way, whether for good or bad, is by example.  The Bible is filled with stories of people who succeeded or failed in certain circumstances.  Their examples of success or faiure offer us compelling lessons on how to live life pleasing or displeasing to God.

Ward Cushman is reflecting on "solitude" and he writes that we can understand and practice "solitude" by following the example of Jesus and offers us six examples to reflect upon.

6 Reasons Jesus Chose Solitude Over People  https://toeverynation.com/6-times-when-jesus-chose-solitude-over-people/

1. To prepare for a major task Luke 4:1-2, 14-15. After Jesus was baptized He spent 40 days praying in the wilderness. After this He was tempted by Satan and then began His public ministry.
2. To recharge after hard work Mark 6:30-32. Jesus sent the 12 disciples out to do ministry. When they returned He encouraged them to separate from the people who were following them to rest.
3. To work through grief Matthew 14:1-13. After Jesus learned that his cousin John the Baptist had been beheaded, He went away by Himself. Yes, even the Son of God grieves.
4. Before making an important decision Luke 6:12-13. Early in His ministry Jesus spent the whole night alone in prayer. The next day He chose his 12 disciples.
5. In a time of distress Luke 22:39-44. Hours before Jesus was arrested He went to the Mt. of Olives and went a short distance away from His disciples to pray. He was in great emotional agony knowing what he was about to face.
6. To focus on prayer Luke 5:16. Many times in Jesus’ ministry He spent time alone in prayer.
