Question: Are Gayatri and Savitri different? 

Ans:

Not exactly. They are different expressions of the Supreme Power of God . As such they are opposite faces of the same coin. Gayatri (idolised with nine faces) and Savitri (idolised with five faces) in fact identify the extra-sensory and sensory excellence in human life which are known as Riddhis and Siddhis in yogic parlance. Gayatri and Savitri are inseparable - inherent like heat and light in fire.
