  Let's say there is a non-linear differential equations like the 
  sol = NDSolve[ {a'[t] == a[t] ( 3 - a[t] - 2 b[t] - 3 c[t] ),
         b'[t] == b[t] ( 2 - a[t] - b[t] ), c'[t] == c[t] (4 - a[t] - 
b[t])}, {a[t], b[t], c[t]}, {t,0,10}]

  Is there a way to systematiiclly specify the initial values to the 
above equation (e.g. in the table format)
  so that you can visualize the multiple trajectories on the same plane 
or in the same 3D space ?
