Having tattooed countless bodies, Geerts has come to see each one as a unique canvas, composed of various parts and shapes. This view shapes his approach to painting, where he explores the human body by dissecting it into separate elements and layering them, mimicking the layers of human skin. Tattooing, with its rich traditions and established techniques, offers a beautiful yet sometimes restrictive framework. The defined lines, the amount of black, and the specific methods all contribute to its timeless appeal. In his paintings, Geerts seeks to break free from these constraints, gradually and thoughtfully. While he continues to honor the traditions that add value to his work, he strives to balance them with innovative approaches.

In contrast to the external focus of tattooing, Geerts' paintings delve deeper into the internal complexity of human existence. They explore the intricate connections between the body and the mind, and how our minds grapple with these connections. This particular series, titled "Inner Fire," is a meditation on reaching, maintaining, and living by one's fullest potential. It is about diving deep within oneself to find and nurture that inner flame. The "Inner Fire" series resonates deeply with Japanese philosophies and mythology, where the concept of inner strength and personal transformation is central. In Japanese culture, fire often symbolizes purification, passion, and the indomitable spirit. The series aligns with the Japanese notion of 'kaizen,' or continuous improvement, reflecting the relentless pursuit of self-betterment and the balance between tradition and innovation.

Moreover, it echoes the myth of the Phoenix, a creature that embodies rebirth and renewal through the purifying fire, mirroring the journey of discovering and igniting one's inner fire.
