Letters to my Mind, Body, and Spirit

Spirit

Dear Spirit,
You are the most mysterious among the three. I can hear your hum when I'm in a quiet room. I have felt you run chills up my spine when I'm deep in thought. But I have never seen your essence. That's what makes me so intrigued. I look at my body every day. The hairs on my head tousled into a messy bun, my hands at work typing on this keyboard. Mind even shows me pictures of itself from time to time. Not like Body does, but in their own unique, sentimental way.
You are also different from Body and Mind because you haven't always been with me. I can remember a time when you were foreign to me like a best friend you meet for the first time. You don't realize it, but they end up meaning more to you than you could have ever imagined,
We met when I was twelve years old. I was stumbling through life, trying to figure out who I was. As soon as you saw me, you picked me up in your big arms and helped me find my identity and what truly makes me feel.
Though we have never said a word to each other, I always feel your presence. I feel you when I look at the cattails that grow amongst the yellow flowers by the woods. You make my hands shake, and my face becomes pale before a big presentation. You whisper sweet words in my ear as I hear guitar-playing love songs. My cheeks turn rosy as the singer's voice turns to honey.
I don't know why, but I think I cherish you most of all. You make me feel.
Though your letter is the shortest of all, it doesn't mean I don't cherish you. We just simply understand each other better than I know the others.
Each time you hum in my ear, I feel less alien. I am finally alive.
Maybe You aren't such a mystery after all.
Yours always,
Ab
