All emotions and feelings are a source of energy. We can look at a painting in a Gallery or wherever you see it , and in our mind comes an episode of our life , may be a pleasant one, enjoyable or less, fear or sadness. Often the emotion plays in artmaking a major role.
Usually an artist express his feelings in his paintings. In fact , art is based on feelings ans emotions. :)
We are emotional beings and is hard to control our emotions. Not the emotions are the problem but the crowd of overwhelming emotions. Anything overwhelming is very unstable. It comes like a wind and passes by, leaving you behind, empty, shattered, in sadness and in sorrow.
Emotion is very fragile, very changing. One moment it seems that is all. Another moment you are simply empty.
I have noticed that I cannot paint if I'm feeling sad or too happy :)... I can do it , but I know that I'll not like the result, that painting will not inspire something , it will be empty. So I prefer to stay away of my canvas in that days. IS MY CHOICE!
I don't care about how many paintings I have to paint in a month. It's NOT quantity that matters.
Often the people ask : "How many hours were taking on this painting? "
My answer? " I don't know" :D
I am always doing that which I cannot do, in order that I may learn how to do it.
