These texts have been drawn from notes taken during Don Bosco's conferences. As can be seen, we respect the writer's style (Fr Giovani Bonetti and Fr Giulio Barberis), but we report Don Bosco's thinking. As he does in his circulars, here the saint emphasises things that he believes are characteristic features of consecrated Salesian life, but with a freshness and liveliness more typical of the spoken word. What emerges is a holistic model of the Salesian in his consecration and of one who is aware of the demands of his vocation, to which he commits himself generously and with all his strength.
