Thank you for sharing the girivalam video. A must for all devotees to Tiruvannamalai. It is believed that Lord Arunachala instantly pardons one’s sins upon completion of the girivalam. I thoroughly enjoyed the girivalam too in 2008!
"Adjust yourself to the realization that you are a divine being, a self-effulgent, radiant being of light."
Jyoti is the Sanskrit word for inner light. To bestow on devotees terms that were more specific, Gurudeva developed the Shum Language of Meditation. In Shum the word for the light that lights up the mind is balikana. During Shum meditation there is an indrawing of forces to realize balikana, a moon-like glow, leading to iftye a deeper kind of inner light which, in turn, leads to milinaka, a sustained iftye which doesn't go away and can be sustained after we've finished our meditation.
