Should one have only one Guru? Or multiple Gurus?
There’s plenty of Gurus out there today.
Some are genuine, and some are scamsters.
And of course many Gurus for various arts and sciences.
Theoretically, anyone who teaches us anything is a Guru in that field.
But the true Guru?
Can only be one.
Because s/he will be the one that dispels the veil of ignorance, and helps us on the path to moksha.
