Once you have spent time in solitude, you return to life in community. It is a rhythm that we all must learn.
A return to the noisy world can be troubling if we believe that our practice of prayer, solitude or fasting has somehow caused us to be suddenly more mature or better than those who did not show as much discipline.
Trusting in God may be a challenge for you if you’re more comfortable trusting in your own spiritual efforts. You may have decided that if you do the ‘right’ things, then God will be obligated to approve of you.
If you fulfill your religious obligations (i.e., go to church, help the needy, not curse, pray, read the Bible, give money, visit the sick, etc.), then God must keep his end of the bargain (i.e., all nothing bad to happen to you or those you love).
You may have reduced the gift of salvation to a mere contract with God. God has become your spiritual business partner.
In solitude we must learn to rest in the mercy of God’s love for the broken, weak person that we really are. God loves us! We return to society with a sober mind and humility. The truth learned and the Presence experienced in solitude will equip us to come out of the prayer closet and love more patiently. Solitude does not need to be lost when you depart from it.
“A day filled with noise and voices can be a day of silence, if the noises become for us the echo of the presence of God, if the voices are, for us, messages and solicitations of God. When we speak of ourselves and are filled with ourselves, we leave silence behind. When we repeat the intimate words of God that he has left within us, our silence remains intact.” 
Think about your reality being transformed in such a way that you hear echoes of God in every noise and conversation. What if your words were transformed by what you heard from God in times of solitude?
Let me leave you with a prayer written by Thomas Merton in his book ‘Thoughts In Solitude’. Say this one aloud.
