Answer in Details
Arunachala is considered the embodiment of Lord Shiva himself, the Agni (fire) Linga among the Pancha Bhoota Sthalams. The Girivalam, performed on Poornima (full moon) days or with true devotion, is believed to burn away karma and spiritual impurities. Many saints, including Sri Ramana Maharshi, have spoken about the immense spiritual significance of circumambulating Arunachala.
May Lord Shiva bless you with inner peace, wisdom, and spiritual progress. Om Namah Shivaya!
