Significance of narakAsura being destroyed by SrI KRShNa

Naraka, which is hell, is nothing but the fluctuating mind. The yoked mind is heaven or svargam. When the mind is agitated it is symbolized as narakAsura having overrun deva loka or svarga loka (heaven). KRShNa as the sAttvic aspect of Pure Consciousness destroys narakAsura with the sudarshana cakra- this is literally the discus of good perception. When everything is seen as the guNas playing with the guNas, that is the sudarshana cakra. Abiding there permanently is the goal, but undoubtedly difficult to achieve overnight.
