An artist is an explorer.

Do remember that one line does nothing; it is only in relation to another that it creates a volume.

Drawing is putting a line around an idea.

Truth and reality in art do not arise until you no longer understand what you are doing and are capable of but nevertheless sense a power that grows in proportion to your resistance.

A new painting is a unique event, a birth, which enriches the universe as it is grasped by the human mind, by bringing a new form into it.
