  We propose a mechanism of high temperature superconductivity from the
viewpoint of chirality and Berry phase. It is observed that spin pairing and
charge pairing is caused by a gauge force generated by magnetic flux quanta
attached to them. From the renormalization group equation involving the Berry
phase factor $\mu$ it is found that there are two crossovers above the
superconducting temperature $T_c$, one corresponds to the glass phase and the
other represents the spin gap phase. Actually, in this topological framework
each charge carrier is dressed with a magnetic flux quantum and represents a
skyrmion. The skyrmion-skyrmion bound state leads to the d-wave Cooper pair
formation. We have also discussed the Magnus force acting on the vortices of
this system.
