[paragraph continues] One should bathe there, O virtuous one, with subdued soul and leading a Brahmacharya mode of life. By this, one obtaineth merit that is greater than that of a Rajasuya and horse-sacrifices. The tirtha called Naimisha is productive of good on earth. Pushkara is productive of good in the regions of the firmament; Kurukshetra, however, is productive of good in respect of all the three worlds. Even the dust of Kurukshetra, carried by the wind, leadeth sinful men to a highly blessed state. They that reside in Kurukshetra, which lieth to the north of the Drishadwati and the south of the Saraswati, really reside in heaven. 'I will go to Kurukshetra,' 'I will dwell in Kurukshetra,' he that uttereth those words even once, becometh cleansed of all sins. The sacred Kurukshetra which is worshipped by Brahmarshis, is regarded as the sacrificial altar of the celestials. Those mortals that dwell there, have nothing to grieve for at any time. That which lieth between Tarantuka and Arantuka and the lakes of Rama and Machakruka is Kurukshetra. It is also called Samantapanchaka and is said to be the northern sacrificial altar of the Grandsire.'
