Arunachala Paraman : Lord Vishnu with four hands darshan
Gadadhara (Vishnu) bearing Shankha, Chakra, Gada and Padma is called Keshava. He is Lord Narayana.
He represents the final culmination of Bhakthi.
Vishnu is Paramatma (The Supreme Soul) and Parameshwara ( The Supreme God). The meaning of Vishnu is the 'vis': to enter, to permeate; 'nu': into.
Hence Lord Vishnu represents the All pervading Force in all. This is nothing but Arunachala. The Substratum of all, the Power in all.
Those who approach Arunachala through the Jnana marga see in it Lord Shiva ( Absolute) and those who approach Arunachala with Bhakthi see in it Lord Vishnu ( The Supremely Beautiful Godhead)
This darshan of Arunachala is Lord Vishnu with His four Arms with conch, mace, lotus and chakra.
This is the Arunachala Paraman Darshan and is a MUST darshan.
