...Or, why are you a monist as opposed to a dualist?
The dualistic path which stresses on submission, unflinching faith, love and devotion to Personal Gods never really appealed to me much.
Its the non-dualistic path of "Jnana" (knowledge of the Infinite Self) that I find more interesting.
In non-duality, the worship of a separate entity is not really necessary because according to this school you ARE the divinity in flesh and you only need to rediscover your true limitless nature.
And still some non-dualists (probably the ones who had a dualistic upbringing) prefers to worship various deities.
They do this to remain humble and keep their mind purified, which they believe is important for the attainment of higher non-dual knowledge whereas other advanced non-dualists simply rely on the teachings of the masters and don't feel the need to worship any forms.
I was a member of the Hare Krishna forum long ago (they're a dualistic group) and to be honest, I found most of them intolerant of other hindu sects and they often displayed online hostility towards the non-dualists.
This is also one of the reasons why I moved away from this dualistic school.
I find the non-dualists more respectful to the followers of other hindu sects. They're always up for peaceful intellectual debates. This is the thing I like most about them. :=)
