The five elements based on Indian mytho are - earth,water,fire,air and space (sky).
Ishu is not just superwoman, she is infact the mata shakthi roop. She escaped from the attack of nature, pancha boothas.
1. Earth- She survived from earthquake and had only small plaster on her forehead.
2. Water- She fought with crocodile in water for her DTS and the poor soul crocodile died.
3. Fire- She saved Adi from fire which actually burst out from gas cylinder😉
4. Air - She hanged Raman upside down in air, full control of vayudev😆
5. Sky- ????
I am not aware of any incidence where she turn down the power of sky. If not happened before, may be in upcoming days she will complete her task and be called panchabootha jeet devi.
