Answer:
Dvaita means 'two'. Advaita means the opposite one ie 'no two'.
Vedanta is veda antha - it means 'extreme of knowledge'.
Those who think that Almighty, the supreme soul ie paramatma
and individual soul ie jeevatma are different and cannot be united in any situation. This is dvaita. But according to advaita philosophy, only one soul ie paramatma which is having a tendency to multiply itself into so many individual souls ie jeevatma. Thus it has immense intelligence to play the hide and seek game. After getting bored with the game finally the individual soul finds the right way to get freedom from its bondage which has been made by its own willingness. This is advaita philosophy.
