The Supreme Sovereign Lord manifesting Himself asBrahma, Vishnu and Maheswara, through the prompting of Primal Will is engaged in creating, fostering and destroying the worlds. In what is thus created, there is always the principle of Dualism. There is difference and disparity between one and another. If these differences and disparities are harmonised wisely, the world will have happiness and peace. If, on the other hand, living beings behave wrongly, the world will be sunk in anxiety, misery and confusion. When these arise, the Lord assumes appropriate Forms and affords necessary protection and correction. He sets right the damaged world, removes the evil forces that caused the damage, and instructs mankind in the science of fostering the right and the good.
