Sani, or Saturn, represents longevity, discipline, authority, ambition, leadership, honesty, perfection, humility, elders, denial, delays, misery, adversity, accidents, conservatism and dutifulness. Its role is symbolized as a servant and Sani's influence is often seen as restrictive and obstructive. These influences are said to be mitigated by blue sapphire. In Jyotish, Sani is furthest from the Sun.
