What is the difference between gam and gum?

[Glayvin 0]

I read that the "gum" (g sound with short u sound) seed sound is related to Ganesha Ganapathi, unity and similar concepts.

I recently came across a mantra that uses the "gam" (g sound with short a sound) seed sound with Ganapathi, and the "gum" with the gurubhyo mantra.

Should I be pronoucing "gam" or "gum" with Ganapathi?

Ganesh is Gam. But it is possible your mantra contains multiple seed letters and both may be present. If it is only a single seed letter it is likely Gam.

That makes sense, thanks.

 

So what principle/principles do/does the gum seed sound represent?
