The Blueprint is Not the Building
Saju translates to the "Four Pillars," which serve as the architectural blueprint of your life. The blueprint states: "This wall is load-bearing; this room gets no sunlight." That is destiny. You cannot magically move the load-bearing wall.
However, Free Will is how you decorate the room. You can place mirrors to bounce light into the dark room. You can choose not to sleep in the cold room. Saju does not dictate your exact actions; it dictates the parameters of the resistance you will face.
Changing Destiny Through Action
If your chart shows a massive "Wealth loss" period coming, destiny dictates that energy must leave your possession. Free Will dictates HOW it leaves. You could lose it through a scam, OR you could proactively "lose" the cash by investing it in hard real estate or donating it to charity.
By making conscious choices that fulfill the energetic requirement of the era, you actively steer your destiny rather than remaining its victim.
