  It is argued that every quark flavor can be described as a lepton that has
been excited by the absorption of a supernatural field, which is defined. In
this context, a minimal irriducible representation of SUSY SU(5) is constructed
exclusively of the chiral modes that correspond to three generations of leptons
(or quarks) and their scaler superpartners. The proposed model predicts a new
quark; a left-handed (non-strange) version of the strange quark.
