Narada Muni continued: The city spoken of as Daksina-pancala represents the scriptures meant for directing pravrtti, the process of sense enjoyment in fruitive activities. The other city, named Uttara-pancala, represents the scriptures meant for decreasing fruitive activities and increasing knowledge. The living entity receives different kinds of knowledge by means of two ears, and some living entities are promoted to Pitrloka and some to Devaloka. All this is made possible by the two ears.
