evar koLLai kondadhu Arunachala
Arunachala! Who was it that came secretly, without even my closest people knowing about it, bewildered my mind and robbed my heart? Who else but you could have done it?
Arunachala resides inside devotees with ego-consciousness as atma (antaratma). What he does in their hearts with his grace, Bhagavan calls as secret ‘yaarum ariyadhu’ as no one knows about it.
Once the ego that acts out of its differentiated nature is destroyed and becomes one with pure wisdom of God/Self which looks different and new, Bhagavan says when one experiences it first time it feels like being bewildered (maruL pidithal, where maruL means deluded/bewildered etc), a state which Bhagavan refers to as ‘madhiyinai marutti’, meaning bewildering the mind. (Note: (TRK says vaalarivu which is wisdom gained from merging with God/divinity/Self. It’s different from ‘noolarivu’ which is knowledge gleaned from books - nool is book, arrive us knowledge).
Bhagavan also talks about this ‘maruL’ in Arunachala ashtakam. Who else can be the thief who can steal the hearts of those that think of you, asks Bhagavan.
