Yes.. I agree with you.
'The belief' must come first, then the ability will follow.
I often communicate with spirit guides, they told me that I have to let go, release my ego programming in order to receive 'the higher flow'. The more I surrender my own will, my own thoughts and be open to receive the flow, the more all will come natural. Like this, my techniques are 'shown' to me, seem to come natural and I try to make them my own. Which is going step by step ofcourse.
It amazes me everytime, how spiritual an ocassion piano playing actually is. It incorporates something as divine as music, with technique and physical ability. So it's an integration of spirit, mind and body. The triad. In my opinion it's really a god given thing (i'm not religious, I have another definition of 'god')
And when we learn of our true nature, find this true nature, a 'higher' music will come to us, filled with love, the most powerfull force there is. (Not the juicy romantic kind of love, but the energetic warm and light energy, it's very powerful indeed) I find that If I open myself to this, more and more do not only technique and physical ability fall into place, seem to reveal them selves to me, they show me the right way for me, and I can accept them.
It's all about opening up, believing, having faith in 'god', (the universal flow) that reaches us, and will in the end completely transform us. Not just our personality but also our physical piano playing. In the end, it will feel 'just right', and the feeling that comes with this is undescribeable beautiful (I'm speaking out of a past life experience regarding piano playing)
