"From the day I saw the most precious eyes, I believed in miracles to the core," she writes. "Such a gift God has given me, exploring in your beautiful worlds every day."
Spears goes on to share the aspirations she has for her sons, and what she hopes to pass down to them. "I pray as a mother I teach you strength and passion to carry through the struggles in the world. Most battles will always be won on your knees. I pray you find your dreams," she continues. "God always comes to us in tiny whispers. I pray you always find his whisper and understand the true meaning behind following your inner voice as well."
The 34-year-old pop star also offers up some advice. "Always believe in yourself and know anything is possible. I pray dreaming awakens your soul to limitless possibilities," she counsels. "I hope the most precious mysteries of life stay with you always and you are never ashamed of how bright your light truly is. I hope you learn praying alone is when you are most connected to God, and know you are never alone. He is with you always."
Spears concludes her letter, writing, "I pray you laugh, love and soar through your journey of life."
The letter to her children comes as speculation surrounds her court-approved personal and financial conservatorships that started in 2008. The New York Times on Wednesday revealed how much Spears' father, Jamie Spears, earns as he continues to co-manage her finances with lawyer Andrew Wallet.
In 2014, Spears spoke to ET about her team. "You just make it work out," she said. "I have really good people around me that support me in what I do in my daily life, and so I'm really blessed."
