The purpose of the Rosary in the Roman Catholic Church is to commemorate certain events in the life of Jesus Christ, and to thank and praise God. There are a total of twenty Mysteries reflected upon in the Rosary, and these are divided into four groups of Mysteries: Joyful, Luminous, Sorrowful, and Glorious.
The Rosary contains five decades, each one a reflection of one of the Mysteries within the Mystery group. Mystery groups are prayed on a certain day of the week or during a particular time of the year.
Following are the Sorrowful Mysteries which are prayed on Tuesday and Friday and during Lent.
1st Sorrowful Mystery – The Agony of Jesus in the garden

In the forsaking prayer to the Father, Jesus found strength, trust, and an angel was sent to comfort Him. So Jesus will be our comforting angel. It’s as He said to us: ” Why do you worry in your difficulties? Be strong in me; look to your God in your most troubled hour, and you will be triumphant.” Let us ask to forsake ourselves to God, to always do His will.
2nd Sorrowful Mystery – The scourging of Jesus at the pillar

How many pains, how many torments, and how many wounds on the body of Jesus? How much blood falls to the ground, while His tormenters laugh, insult him, and gather their strength to hit the innocent body of Jesus again? Let us ask to accept every insult for the love of our Lord, and also a true regret for our sins.
3rd Sorrowful Mystery – The Crowning with Thorns

Think of the indignity, outrage, pain, and humiliation that Jesus suffered. They striped Him of every dignity, He was treated as the guilt of our worst sins. He seems to say to us: ” Why do you despair when you suffer? Is that the way you love me? Meditate about my passions and find in them great riches.” Let us ask the gift of patience to accept all humiliations, thinking of how Jesus suffered for us.
4th Sorrowful Mystery – The Carrying of the Cross

Even if He had suffered just for you, Jesus would have accepted such pains, great is His love for you. Along the road to Calvary Jesus sees Mary, His Mother. Can we imagine the moment when Their eyes met? Oh how Her Heart must have ached. Let us pray to Mary for the grace to always accept our cross, so that Her and Jesus may bear it.
5th Sorrowful Mystery – The crucifixion and death of Jesus

Jesus wishes to see us close to His Mother; He wishes that, like children, we keep our hand in the hand of Mary. That is what He wants. He asks us to look to the heavenly Mother, that is depend on Her. He asks that we accept Our Lady as our true Mother, who will ignite in us a fervent love of Her Son. Mary, we trust in You, take us and put us in the refuge of Your Immaculate Heart, heal with Your humility our pride, that so often takes us far from God.
