Once, in Kasi, when Sri Sankara was going to the Vishwanath Temple, his path was blocked by an "untouchable" who was accompanied by his wife and 4 dogs. The disciples of Sri Sankara shouted at him to make way, and to keep a distance. The untouchable smiled and said, ""According to your principle of Advaita, which you practice, all the Jivatma are same as God. How do you ask me to go? How am I different from your Paramacharya? What you say is unreasonable. How can I go away from myself?" Sri Sankara realised that it was not an ordinary person and understood that it was Lord Shiva himself who had come along with His consort and the four Vedas. He prostrated before the Lord and sang five slokas called "Manisha Panchakam". Lord Shiva presented himself along with Visalakshi and blessed Sri Sankara.
How can Sankara prescribe such rituals when he himself practiced Advaita Vedanta
