What Is The Difference Between Self Inquiry And Mindful Meditation?

[Mohsinuddin]

I'm confused between this two. I just realized self inquiry is totally different than mindful meditetion?

[Truth]

Mindfulness increases your awareness, Self inquiry helps you find answers about who you are in truth, looking at yourself very objectively and honest.

 

[ZenMonkey]

Self inquery is like looking into a mirror. Meditation is like watching the clouds passing by.

[Gavalanche]

Should the two be practiced separately? Does self-inquiry bring about any of the physiological benefits attributed to meditation?
