mac00uk reacted in Swaminarayan Mantra?
Sorry Abhishek but you have derived an incorrect meaning. For SWAMINARAYAN to mean SWAMI+NARAYAN as in two nouns it is wrong for sanskrit grammar.
SWAMI acts as an adjective to the noun NARAYAN so that NARAYAN (as in God) the SWAMI (master/lord) of all.
It is not two distinct entities, for if it were then the name would be SWAMINARAYANAU
Your theory is therefore flawed and incorrect.
