Poarattam kaat Arunachala
Once a person becomes Self realised, for him or her there is no appearance and disappearance of the material world that is samsara (poakkum varavum literally means goings and comings), Saint Manickavasagar says ‘poakkum varavum illa puNNiyane’ about Siva). In such an expanse of chidakasa (bliss consciousness) destroy the army of my ego with your immeasurable grace Arunachala, says Bhagavan.
The constant battle (from time immemorial) between divine grace and ego consciousness (between good and evil, or devas and asuras - the representatives of the good and the bad, respectively) is called devasura battle. In the fight between the grace-personified Siva bodham and delusion-filled ego consciousness, it is the divine force that wins in the end, hence it’s called aruL poarattam = divine battle/struggle.
This battle which takes place in the heart space is an interesting spectacle. Desiring to witness it, Bhagavan, like a person who climbs to the top of a hill to watch elephants fighting below so he doesn’t get hurt in the process, wants to watch it from the peak of of Arunachala, the hill of wisdom, and prays to the lord to show him the spectacle. Such a way of seeing, from the edge of gnana (wisdom) is called ‘saatchi vruthi’ by ancient seers.
