शोणाद्रिनाथाष्टकम्
ŚOṆĀDRINĀTHĀṢṬAKAM
Śoṇādri means “the Red Mountain” and is an ancient name of Arunācala. Śoṇādrinātha therefore means “the Lord of Śoṇādri,” referring to Śiva as Arunācaleśvara.
The hymn praises Śiva in several aspects: as Rudra and Maheśvara, as Ardhanārīśvara, as the cosmic Lord with the Sun, Moon and Fire as His eyes, and especially as Tripurāntaka, the destroyer of the three cities.
This is a very rare hymn which is barely known or recited today. My ācārya Somaśekhara śivācārya stressed this a lot on us and we ensured that it was chanted during almost every ritual. Somaśekhara śivācārya says that this hymn is unique and non-comparable to other compositions as it is from the śaiva āgama-s, and hence, from the Lord directly.
