Can someone please translate and share the context of what this man (who is supposedly Lord Shiva in disguise) is saying to Adi Shankaracharya ji?

This depiction is supposedly a based on a true imteraction between Adi Shankaracharya and a man he meets while walking on the road, who is apparently Lord Shiva himself in disguise , with a deep spiritual meaning. Hope someon could please translate it. Har Har Mahadev 🕉 🙏
