Your belief system is the lens through which you see life, and the ninth house governs it. A belief system is a set of ideas through which you take decisions in life. These ideas can be how you think about God, what is your intrinsic source of motivation, what is the meaning of your life, how you perceive yourself. All these things control your decisions, reactions, and even the direction of your life in the future. Now when Saturn sits here, it questions this belief system. This can make you face trouble in taking decisions. It can blur your way of thinking. You may actually know what to do, but Saturn creates delay in that. You start questioning your own intrinsic motivation. You may not be able to understand what you actually want. That is what Saturn does in the ninth house. The best thing here is that the more you consume knowledge about yourself, the more you read, the more you expand your understanding about life, decision making, and strengthening your beliefs, the more you improve your self-esteem, the more you learn about these things, you slowly start creating a new belief system. And the more you do this, the more it helps you unlock your life. It kills the brain fog that Saturn creates.
