Lawson titled her letter, “You Have Been Such a Blessing to Me."

Tina Knowles Lawson penned a Mother's Day letter to her daughters Beyonce, Solange Knowles, Kelly and Angie.

In the TIME article titled "You Have Been Such a Blessing to Me," Lawson addressed each of her four daughters – Beyonce and Solange are her biological children — and shared her memories of each of the women.

"When I was asked to write an open letter to you, I thought about the hundreds of texts and emails that I have sent to you on holidays and on Sundays, when I ask you to say a prayer to thank God for each other. Every day, I wake up thinking about how much I love, admire and cherish each of you," Knowles opened the letter.

She first addressed Beyonce, and wrote how she wished that people could witness who the singer is and how she acts behind the camera.

Beyoncé, I wish people could see how you are when you’re not in front of the camera or on the stage. How compassionate and kind you are to people, how you look them right in the eye when you speak to them. How hard you work, how generous you are with your time and money. How you don’t care if anyone knows about it because you do it from the heart. I wish they could see you with the Make-A-Wish Foundation kids, how patient you are and how your love has helped to extend lives. Yes, you are a huge star, but you have somehow managed to stay grounded and humble in the wake of all your success.

Knowles next addressed Solange and called her "rebel warrior," her daughter that always fought for what she believed in.

Solange, I knew when you were born three days late that you would walk to the beat of your own drum. You were always my rebel warrior! Always defending the underdog and fighting for what you believe in. I remember you, at 10 years old, started a petition to remove a bad teacher, and your dad and I were so proud of you. I love that you do not let others define who you are, or what you are. Whether in your music, fashion or your life, you truly are your own incredible, unapologetic person! As tough as you are, you will drop everything to take care of someone you love.

The letter went on to address her love and memories of Kelly and Angie before sharing her proudest moment with the four girls: "I would have to say it was at my recent wedding, when all four of you said in your own words that I taught by example and that I helped to make you the women you are today!!!!"
