There are some Deities in Hinduism who are called with the epithet Iswara.
Lord Shiva as Parameswara.
Another is Sani, Saturn.
The pronunciation for Saturn in Sanskrit is Sanaiscara, one who moves slowly. as Saturn takes 30 years to orbit around the Sun.
Special status is bestowed on Sanesswara.
He grants boons after he tests you.
No real harm befalls one.
There is a special prayer for Saneswara, Sanai Vajra Pancharika Stortram.
This helps in reducing the mental tensions that occur when Saneswara is not favorable in your Horoscope.
