Meditation and Piano Playing

I have been spending at least an hour every day meditating, using Holosync® by Centerpointe.
One of the unexpected discoveries I have made is how weak my left hand piano playing was. My left wrist was injured years ago, and my left shoulder has been tense and sore ever since. I have tried many therapies and exercises to ease the tense muscles, Holosync® meditation has been the most help. Now, my left hand and arm feel the same flexibility as my right!
I am working very carefully at the piano to develop left hand technique, using Bach 2 part Inventions. Sometimes I go over a short phrase many times with the left hand to get the right feeling. I want to make sure that I am always releasing are weight into the keys from the shoulder, and never reaching for the keys with the fingers.
I am discovering many new sensations in the left hand, especially at the bridge, the base of the fingers. I must have been holding my arm and hand very rigidly.
I have been looking through music to find left hand sections to use to practice. One of them is from Debussy’s 1st Arabesque:

In the past, I was holding the bottom note and reaching with stiff, straight fingers, and was always struggling with this section.
Starting with the 3rd bar, I concentrate on moving the whole arm to the first note of each phrase, and lifting at the end of each. I make sure that I am moving the hand and arm to reach the keys as I hold the half notes. I make sure that my fingers are curved under as the hand rolls back and forth through each phrase.
I have worked on improving left hand technique for many years, but with little success. Now my left hand feels like it is waking up. I can’t know for certain, but I am sure that Holosync® meditation from Centerpointe has made the difference.
