You cannot drive out rajas and tamas, you can only convert them and give the predominance to sattwa. Tamas and rajas disappear only when the higher consciousness not only comes down but controls everything down to the cells of the body. They then change into the divine rest and peace and the divine energy or Tapas; finally sattwa also changes into the divine Light. As for remaining quiet when tamas is there, there can also be a tamasic quiet.
