According to Bose-Einstein statistics, there exists a Bose condensate for collections of bosons. What does this mean?
The Bose condensation phenomenon occurs for low temperatures T less than a critical temperature TC where all particles reside in the lowest state. For T < TC (critical temp.), all particles reside in the ground state
