By Swami Harshananda
Sometimes transliterated as: Arsa-linga, ArSa-liJga, AArsha-liyga
Ārṣa-liñga literally means ‘linga pertaining to the ṛṣis’.
There are two types of liṅgas
The second one is classified under nine heads. The ‘ārṣa- linga’ is one among them. It is defined as the liṅga set up and worshiped by ṛsis or sages. Ārṣa-liṅgas are usually spheroidal in shape, resembling an unhusked coconut fruit, and do not have the brahmasutra mark on them.
