The first set of Sefirot is called The Three Upper Sefirot. This is because they correspond to the intellectual faculties. They are also called Mochin (Brains). They are:
1) Keter (Crown), which corresponds to the quality of pleasure and desire. (There also is a Sefirah called Da’at (Knowledge), which is actually one with the Sefirah of Keter and corresponds to the aspect of focusing and connecting to a subject. This Sefirah represents the intellectual interest into a subject, which relates to the aspect of desire.)
2) Chochmah (Wisdom), which is the ability to have a new insight into a subject. All wisdom derives from this Sefirah.
3) Binah (Understanding or Comprehension), which corresponds to having a comprehensive grasp and understanding into the subject by way of detailed analysis.
