This quote by Leonardo da Vinci suggests that a good painter should not just focus on the physical appearance of a person, but also strive to capture the essence of the person’s soul or their inner feelings and intentions. This is a profound concept that goes beyond the surface-level representation of a subject, pushing towards a deeper, more meaningful portrayal.

In the first part, "a good painter has two main objects to paint, man", da Vinci refers to the physical or external aspect of painting. This includes the technical skills needed to accurately depict the human form, such as understanding of anatomy, light, shadow, and perspective.

The second part, "and the intention of his soul", delves into the psychological or internal aspect of painting. This involves capturing the subject’s emotions, thoughts, and personality. It’s about conveying the invisible aspects of a person that are just as, if not more, important than their physical features.

Applying this idea to today’s world, it can be seen in various fields beyond painting. For instance, in photography, a good photographer doesn’t just take a picture of a person, but captures a moment, an emotion, or a story. In writing, a good writer doesn’t just describe a character’s appearance, but also their thoughts, feelings, and motivations.

In terms of personal development, this quote encourages us to look beyond the surface, both in ourselves and others. It’s about understanding and acknowledging our inner feelings, motivations, and intentions. It also promotes empathy, as we strive to understand what others are feeling or intending, not just what they are showing on the outside. This deeper understanding can lead to better communication, stronger relationships, and personal growth.

In essence, da Vinci’s quote is a call to look beyond the surface, to strive for a deeper understanding and representation of ourselves and others, whether it’s in art, in our work, or in our personal lives.
