My recent reading of Osho, brings a quote to mind that he used as a daily manta-“Touch the feet of one who knows himself.”
Once an artists has let go of the system in social and artistic regimes, he is able to create work that is from oneself. Van Gogh and Cezanne were examples of painters who followed this mantra. These two artists went through great sacrifices and ridicule before they were recognized as pioneers in the arts. We owe them so much not in only respect but for the great respect they had for themselves in following their own way of painting.
