Now upstairs, there is only room for two people on the summit. So Parvati tried to bring Shiva out of his ecstasy. She said, "That person has just come up". But Shiva Tandav was still absorbed in music and poetry. Eventually, Parvati was able to bring him out of the musical thrill. And when Ravana reached the summit, Shiva pushed him down with his foot and knocked him down. Ravana slipped down from the southern face of Kailash. It is said that his drum was slipping behind him and as Ravana went down; his drum went from top to bottom on the mountain, drawing a streak. If you look at the southern face of Kailash, you will go up from the middle. You can see a trail below.
