The conscious mind handles less information because it works slowly and deliberately.
It’s designed for deep thinking, decision-making, and reasoning — things that require focus and analysis.
The subconscious mind, on the other hand, is like a high-speed automatic system. It runs patterns, habits, emotions, and body functions without analysis — so it can process huge amounts of sensory data very quickly.
Because deep thinking takes more time and energy, the conscious mind can only process a tiny fraction of what the subconscious handles automatically.
Looking back over my life my subconscious mind has caused my conscious mind nothing but suffering.
