21. Description of the hymn of praise to the Lord composed by Dhruva; the Lord instructs Dhruva: “I shall give you the foundational position of the wheel of luminaries; even so, go with me to Kāśī; having worshipped the liṅga there, achieve your purpose”; the Lord departs with him to the city of Kāśī; there Dhruva achieves his purpose by establishing a liṅga, and returns home. 90 1
