ELOHIM" (or Elohay) is the first name for God found in the Bible
YHVH" is the Hebrew word that translates as "LORD".
YHVH comes from the Hebrew verb "to be" and is the special name that God revealed to Moses at the burning bush.
hindus call him BHAGWAN.....
sounds more like a language issue that which of these god's really exists
ur statement abt muslims not accepting if hindus call god as bhagwan, it goes for every religion who would prefer to call god by the name as taught to them in their religious books.
