Vaheguru

[Guest balvinder singh]

this may be a silly question but i guess im just curious, i was just wonderig why the word 'vaheguru' doesn't come up that much in sri guru granth sahib ji mahraj, i did a search online and there the word vaheguru is not mentioned a lot, where as words like raam are mentioned alot, this amde me curious and my question is which guru introduced this word and why do we do vaheguru japna instead of any other name for god (i know you can also use another name for god to do simran but im just curious as to why we do waheguru simran most of the time) i know this may be a stupid question and forgive me if ive said anything wrong, thank you
