Canto 3 -
Araṇya-kāṇḍa
Chapter 73: Kabandha Requests Śrī Rāma to Visit Śabarī
Text 3.73.31

उदारो ब्रह्मणा चैव पूर्वकाले विनिर्मितः॥

udāro brahmaṇā caiva pūrva-kāle vinirmitaḥ

udāraḥ = that wonder; brahmaṇā ca eva = by Lord Brahmā; pūrva-kāle = in the ancient past; vinirmitaḥ = was created.

That wonder was created by Lord Brahmā in the ancient past.

For some reason, [Lord Brahmā] had blessed [the mountain] by saying, “May it become a wonder!”1

Its wonderful nature is described in the next [two verses].

1 According to the commentator, udāraḥ actually means praśastaḥ which refers to something excellent. We have rendered it as “wonder” in the sense of “the seven wonders of the world.”
