“Bobby was like a Zen master,” de Leon was once quoted about his late mentor Chabet. “He taught me how to behave. Maybe he felt I was too loud, talkative, boastful. I cannot really tell what I was to him. Bobby and I used to go swimming every morning; we’d do lapping. Some thought I was a Chabet boy, but I wasn’t really a groupie. May pagkasutil din ako. For the most part, I was absent in his group shows".
de Leon usually shows the method of compositing imagery through the Rorschach Effect: “You fold, unfold. If they match, then it’s done".
Alice Guillermo wrote in Asian Art News September/October 2005: “These works by Ramon Manuel de Leon are highly original and valuable because they serve to remind artists that visual power is the fruit of a long conceptual process. Important art is not only appealing to the eye but intriguing to the mind as well".
