Buddhi is explained as "intuitive intelligence". Whatever it means, it is not mere intelligence.

A Prof said in a CBC BBC programme that gut feeling/intuition is not a crude way of decision making but is based on more sophisticated mechanism that we do not understand yet. It was shown that partial ignorance can help in better decision making! (Something my grandmother knew too!)

Logic has limits. Incompleteness theorem hints intuition might not be a bad thing at all.

Where are we heading? Other day I just realised even my head is incomplete! I could not understand whole mess about formal systems.
