Jaya this story was posted by Anjani yesterday so not entirely DKDM puran. Read on.
Shani has boon from Parvathi according to scriptures, that no work
would begin with out his drishti. Shani despite his bad reputation, is
not that bad. He does a lot of good as well. It is karma that is
reflected in our lives. Just like Yama, Shani is also known as sama
drishti. Shiva himself gave him the title "eeswara". No other graha has
been bestowed with this honor.
This is what I found on the web fro Puttaparthi Swami Vedic Astrology website :)
There is a tale of Parvathi wanting a new abode in Kailash, and
when Siva (finally) granted the wish for an abode, Lord Brahma demurred
and told, "Not wise, not wise!" for he could sense the gaze (drishti)
of Shani would bring matters to grief. Siva went to ask Shani to avert
his gaze from the new house. To cut a long story short, there was
misunderstanding of the signals, Siva beat his dhamaru (because he was
doing the tandava dance for Shani), Parvathi misunderstood the message
and burned the house down. The moral of the story is that none may
escape the drishti of Shani.
