Narayana means the One who has four hands". It is famous that Maha Vishnu has four hands and they carry the Conch, the Discus, the Mace, and the Lotus. Very many of us in the enchantment of the immediate sense-joys refuse to listen to the small inner voice of conscience, the sound of the Paanchajanya-conch, and so He wields the 'Mace' and we come to suffer small calamities and tragic jerks in our smooth existence -communal, social or national. If still the individual is not listening to the call of the 'Conch', the wheel-of-time, Chakra annihilates the entire. The Shila has perfect impressions of Narayana at the top periphery of the Shila. All these four are wielded by the One Infinite Blue-bodied Narayana, clothed in His 'yellow garb', manifesting to maintain and sustain the world of good and evil. Since the Self functions thus in a four-fold pattern, Vishnu has the appellation, "the four-armed Lord."The Shila bestow the devotee with utmost strength and makes him very quick good decision maker. He emerges out to be the best at the crises management. The Shila is extremely smooth, perfectly shaped, lustrous, small sized, cold to touch, has flawless impressions.
