[Canto 4, Ch. 25]

The southern gate of the city was known as Pitṛhū, and through that gate King Purañjana used to visit the city named Dakṣiṇa-pañcāla accompanied by his friend Śrutadhara.

As long as one is attached to the enjoyment of material resources, he hears from the right ear and uses the five senses to elevate himself to the higher planetary systems like Pitṛloka. Consequently the right ear is here described as the Pitṛhū gate.

PURPORT
The two ears are situated on the northern side and the southern side. The ear on the southern side is very strong and is always anxious to hear about sense enjoyment. The ear on the northern side, however, is used for taking initiation from the spiritual master and for gaining promotion to the spiritual sky. The right ear, or the ear on the southern side, is called Pitṛhū, which indicates that it is used for attaining the higher planetary systems known as Pitṛloka, but the left ear, which is known as Devahū, is
