The sages performed there a sacrifice of a thousand years for heaven and the worlds (SB 1.1.4); they sat on in the long sacrifice with Hari's stories as Kali arrived (SB 1.1.21).
Naimisharanya
नैमिषारण्य
Also known as वैष्णवक्षेत्र · Vaishnava-kshetra (sacred field of Vishnu) · अनिमिषक्षेत्र · Animisha-kshetra (abode of the Unblinking Lord)
Naimisharanya is one of India's most ancient sacred hermitage-sites, identified with the Misrikh-Nimsar region of present-day Uttar Pradesh (Sitapur district); in the Puranas it is the tapovan where assemblies of rishis gathered and where puranic narration took place. In the processed verses it is called Animisha-kshetra, the field of the Unblinking Lord (SB 1.1.4), and Vaishnava-kshetra, the sacred field of Vishnu (1.1.21). Here the sages headed by Shaunaka performed the thousand-year sacrifice for the worlds' welfare (1.1.4), and — knowing Kali to have arrived — remained seated in the long sacrifice, delighting in Hari's narrations (1.1.21).
