The word 透过 is formed by combining two characters, each contributing a layer of meaning to create a new, metaphorical concept. The first character, 透, carries the core idea of "penetrating through" or "being transparent". The second, 过, means "to pass" or "to cross". When fused, they move beyond a simple physical sense of passing through a material object (like light through glass) to express the more abstract idea of "by means of" or "via", as if one's perception or understanding is passing through a medium to reach or comprehend something else.
