There are also 3 other mysteries I favor the most:
First is the Annunciation.
Two obvious aspect is God shows to us how Mary is sinless when the angle Gabriel said “kecharitomene” and "the WOMAN WHO WILL CRUSH SATAN’S HEAD(Genesis 3:15).
Another aspect is shown is that how Mary is humble, and continues to be humble seen in the 2nd joyful mystery. She didn’t say “Yes, Please”, instead she said “Be it done unto me according to thy word.”
It also shown in the Visitation to Elizabeth, how she didn’t say “I’m the Mother of God, bow down”, instead she showed how humble she was.
Secondly. is the Scourging on the Pillar(or Jesus is Scourged).
It shows how he is scourged for our sins, and reminding us that we have to punish our bodies.
Yes, punishing bodily desires is pleasing to God. Mortifying ourselves from impurity, our beastly tongues, of our eyes that looks at everything, and our minds that demons play with.
Lastly, is the Coronation of the Blessed Virgin Mary, the most humble Mary coronated by the 3, persons, but 1 God, Father, the Son, and the Holy Ghost. Showing how Mary is powerful, but remains her humility. This mystery itself gives us Eternal Happiness.
Like what she promised to St Bernadette, “You will not be happy in this life, but I promise you will in the next.”
Obviously, we also have to not take this for granted, we must also endure many sacrifices and pains along the way. The Devil as well will try to make us sin through impure acts and uncontrollable words. But, we also ask Mary to let us hide under her mantle, the devil and his abominable demons are afraid of her, making him and his “friends” flee away from us.
