Filament Mountains

There are many mountains arranged around the foot of Mount Meru. As Mount Meru resembles the pericarp of a lotus flower, these mountains resemble the filaments of the lotus flower, therefore they are called filament mountains. Some of the names of the filament mountains are: Kuraṅga, Kurara, Kusumbha, Vaikaṅka, Trikūṭa, Śiśira, Pataṅga, Rucaka, Niṣadha, Sinīvāsa, Kapila, Śaṅkha, Vaidūrya, Jārudhi, Haṁsa, Ṛṣabha, Nāga, Kālañjara and Nārada.
