I can only describe the creative process with this picture.

The great problem is whether the seed surfaces to the light at a favourable moment, the rest will happen by itself.

I would try in vain to express in words that boundless feeling of bliss, that comes over me, when a new idea opens up in front of me and begins to take final shape. In such moments, I forget everything, and act like a madman. Everything inside me begins to pulsate, and to shake: I hardly start to draft, until one thought overruns the next.

And further: If the condition of mind and soul, we call inspiration, lasted a long time without interruption, no artist could survive this.
The strings would snap, and the instrument would be smashed to pieces. It is alreadygreat if the main idea and the main lines of a composition come to you without much mental activity, as a result of that super- natural and inexplicable power we call inspiration.”
