Purity isn’t about how hard you try or don’t try. You have to jettison that idea out of heart & mind as soon as possible.
Purity is a gift from Heaven that we receive. I personally believe that it is an exceptionally difficult issue for men today because not only do they lack the company of women - real company - but they are unaware of how they are suppose to satiate that desire in the first place. Because of distortions in the culture, which are motivated through hell’s efforts, we all too readily think of female company strictly in its sexual sense. And indeed, many women themselves - who are captives of hell - willingly present themselves as sex toys, not as miracles of Heaven.
But, even if you lack the holy company of women that you are suppose to have in your life, you always have access to Heaven. You need to fall in love with Mary, completely. You have to allow her to have command of your soul. You have to be willing to die for her in an instant. If you do this, like Adam, you will be given purpose, and you will no longer be lonely, because you will have the love & tenderness of your other half. You’re a man. You have to have someone to fight for. When God said “It is not good for man to be alone” this applies to the entire sex. Single, married, religious, priest. It makes no difference. Men need women. It’s how God built you. If you don’t have that, you become like the billions of men in the world that attempt to satiate that gnawing urge through their carnal passions. It won’t work.
And when you start your Marian devotions, it doesn’t matter how much you feel. What matters is the action, not the emotions behind it. If you want emotions, find a bottle of rum. If you want results, then pray, whether you “feel” like it or not. Just make your first petition this, “Mary, I am a sinner, and I have a hard time even grasping my need to pray to you in the first place. Pray for me that I will fall in love with you and that I will persevere in praying to you and loving you every day of my life. I know that it is morally impossible to be saved unless you will it, so I give you sovereignty over my entire mind, and my entire heart, and my entire soul, and my entire strength. I look forward to the day that I will get to be with you forever in Heaven, where I will never cease to love you or be loved by you, my Mother, my Lady, my Love, my Queen. Amen.”
Pray to her, and pray to her daily. When you feel anxious, go to her arms. She’ll take care of the rest.
