The rhythm of relations of color and size makes the absolute appear in the relativity of time and space.
Let us note that art - even on an abstract level - has never been confined to 'idea'; art has always been the 'realized' expression of equilibrium.
Everything is expressed through relationship. Colour can exist only through other colours, dimension through other dimensions, position through other positions that oppose them. That is why I regard relationship as the principal thing.
All individual thought is dissolved in universal thought, as all form is dissolved in the universal plastic means of Abstract-Real painting.
Art is the path to being spiritual.
