Hare Krishna. That verse is from Brhannaridiya purana 38.126. Naradiya purana and Brihan-Naridya puran are two different texts. The following is quoted from Wikipedia which, in my experience, is NOT always the best source for Vedic scripture and Vedic history but here I find it correct so far the difference between the two Vedic texts goes.
"The Naradiya Purana (Sanskrit: नारदीय पुराण, Nāradīya Purāṇa) or Narada Purana (Sanskrit: नारद पुराण), are two Sanskrit texts, one of which is a major Purana of Hinduism, while the other is a minor Purana (Upapurana). Both are Vaishnavism texts, and have been a cause of confusion in Purana-related scholarship. To prevent confusion, some scholars sometimes refer to the minor Purana as Brihannaradiya Purana.
Unlike most Puranas that are encyclopedic, the Brihannaradiya text is focussed almost entirely on Vishnu worship, while the Naradiya text is a compilation of 41 chapters (20%) on Vishnu worship and rest of the chapters (80%) cover a wide range of topics including a large compilation of Mahatmya (travel guides) to temples and places along river Ganges, and neighboring regions."
