A strong Saturn in chart also makes a native quite immune to much dreaded Saadhe-Saati and Kantaka Shani; but it should not be taken literally–the impact of transit of such a big and slow moving planet is felt by every native, be it a transit through an auspicious house or an inauspicious house; but in case of aforementioned natives, these transits don’t wreak much havock on them because of the strength conferred by the radix chart.
Jyotisha is not superstition and it’s also not a pseudo-Science; it’s a proto-Science and it works by way of Karmic scripts written in our subconscious. A strong Saturn in a person’s chart doesn’t magically make a person powerful: It makes him a hard worker first. He is very persistent and works his way through all odds, at a slow and steady pace and wins the battle. He also becomes a hard-task master who loves justice and that’s why he becomes a leader.
