Ayurveda explains our thought process by breaking it down like this:

-Manas is the mind.  It senses things outwardly.  It relies on the external to give it an impression to focus on.

-Buddhi is intelligence.  It perceives both inwardly and outwardly.  Buddhi can reason, and put together information based on what we see and what we feel.

-Chitta is consciousness.  It feels internally, instinctively, with its own sense of deep knowing.

In addition, there are collective and cosmic counterparts of the mind.  The collective is the sensory activity of everyone on Earth.  We can sense this, and the media broadcasts some of this.  The cosmic is the sensory activity of all creatures in all worlds over all of time.  We can connect to the cosmic through meditation.
