Judging Whether Lines Are Parallel Relies on the Analytical Thinking of Consciousness

Question: When looking at a set of lines that appear non-parallel at first glance, is this perception of non-parallelism discriminated by eye consciousness or by mental consciousness? Later, when they appear parallel, is this contradictory perception arising from mental consciousness, or is it a conflict between eye consciousness and mental consciousness?

Answer: The shape of the pattern belongs to form, which is a mental object and falls within the domain discriminated by mental consciousness. Eye consciousness perceives only color; all else is content discriminated by mental consciousness. Determining whether lines are parallel or not is a judgment made by mental consciousness through analytical thinking. When mental consciousness cannot definitively determine the perception, contradictory feelings arise, making it impossible to finally settle on whether the lines are parallel or not.
