No deliberate activation is not always required. For direct learning it is even avoided.
Text for study or courses ... where you want the information consciously as quickly as possible deliberate activation is the way to go. One technique is to PR book/chapters the night before a class and during the class/lecture allow the book to activate. In this case activation is not deliberate in the term of drawing mind maps, working with the book till it 'gel' activation.
