Herru Yoga created a motif of collective trauma to tie together the narratives of his paintings. Collective trauma is formed due to the condition of society that experiences structural violence and physical threats, especially war. The first is invisible, and the second is the destruction of mankind. Instead of choosing gloomy colours to depict the tragedy of war and death, Herru Yoga's canvases instead display a paradoxical brightness. Scribbles, bright strokes that give pressure, curved lines that are free from the 'boundaries' of their objects, seem to present waves of joy. In fact, he combined the dramatic chiaroscuro technique of the Baroque era and the style of abstract expressionism in his paintings. A dominant blue-green background appears in his paintings, momentarily bringing back our memories of the charm of the mountain-sea landscapes of Indonesian painters in the past. But the flat background in HerruYoga's paintings is 'zero reality', an absence that allows the chaos of his objects to be present.

After Guernica is a reinterpretation of Picasso's Guernica (1937), a universal icon of the banality of war. War has never ended to this day, from Gaza to Myanmar. The banality of war triggered Herru to present the deformation of the body like a pipe or the distorted appearance of a crushed human being. The Black Funeral raises a lump of collective grief and an unspeakable sense of loss. Breaking the Silence is a visual metaphor for the urgency of speaking out amidst the false normality of today's politics. Herru Yoga's style was developed from portrait studies and depictions of the body found in the paintings of Francis Bacon (1909-1992). Bacon is famous for his sensation or twist in painting 'Figures'. Namely, Figures that 'form shallow depths, hollow volumes, which determine curves'. The body that Bacon depicts is not an organism or an organization of organs. The body in this case is like an 'egg', namely the state of 'the body before organic representation'. Bacon's intensity in depicting the body that goes beyond the limits of the organic has inspired Herru Yoga to depict the tragedy and banality of humanity.
