"PRATHAMO SHALIGRAM HAIN, DOOJA PARASRAM
TEEJE RAJA RAM HAIN, CHOUTHE ATAM RAM.
RAME NIRANTAR ATMA, SAB GHAT ATHO YAAM.
VAHI TE SANTAN DHARO, RAM TAHI KO NAAM."
The first is Shaligrama. The seconde os Parasurama. The third is the King of Ayodhya and the fourth is Atma Ram, the Soul which permeates continuously within everyone's heart. That is why saints have named it 'Rama'.
