As per Advaita philosophy, the ultimate goal of an Atma is to merge into its source, the Parmatma just like drops of water merge into the ocean but my question is how and why do Atma and Parmatma split in the first place?
Did they even split? The split is only an illusion. A must read is the story of two birds in kathopanishad. Therewere no two birds! That was an illusion or dream or whatever..... Advaita vedanta doesnt say you must merge into god! It says you are god! You dont have to reach to a destination. You were always there!!! So there is no split and it is only maya or adhyasa that makes us feel that there is a split.
