The lord of justice Shani Dev has Saturn as its ruling planet and is one of the Navagraha as per Hindu astrology. The Saturn god is the supreme authority which gives out the fruits of your hard work. It is believed that your karma decides how your life is going to be and Shani Dev makes sure that each individual gets justice. Depending upon your deeds—good or bad, the circle of justice works.
The lord is often associated with fear and many try to invoke superstition among people. However, if your deeds are right and you work hard genuinely, trust the lord to be with you and remove all your worries.
Shani Dev is the son of Sun God (Surya) and his wife Chhaya. Planet Saturn is an embodiment of Shani Dev, and Saturday is the specific day in the week associated with the lord.
Don't forget to pray to the lord who listens to all those who have a pure heart, mind and soul
