Dear friends

I recently read Bhagavad Gita translation... I was thinking there were only 4 types of yogas... but it mentioned about Gnana Karma Sanyasa Yoga as taught by Sri Krishna as an ultimate Yoga, which never heard much about earlier... Can anyone explain better about that..?

Starting with, let me try to clarify that Karma Yoga by simple statement: Do your duty without expecting personal benefit... correct enough? Jnana yoga mean to attain knowledge by studying scriptures... is this ok? If then, what does Jnana Karma Sanyasa Yoga mean? is the question.

Thank You
