Yes, it is an imitation of nature. Nature is made directly by the Artist and art is made indirectly through the pen of the artist. Nevertheless, art is the finishing of that beauty which begins to manifest in nature. A person who has not come to this conception of art he does not yet know the divinity of art. And now coming to the question what art has to do with personality.
Personality is art itself and the greatest art.
It is all art, it is all the way for individuality to culminate into personality. In the ancient times, the religious education and human culture in every form, mainly had personal culture as the central theme of education. And today we are expected to learn mathematics, geography, history and something else, and never the art of personality which is of greatest use in life. Apart from its spiritual significance, in our everyday life we see a salesman who is pleasant, who is courteous, whose manner is well, be a successful salesman. If a seller lacks manner, if he is repellent, he may have all beautiful things in his shop, he will have no success.
