MODELLI DELLA MENTE"Gratefulness" è un testo pubblicato recentemente, uno dei pochi disponibili in italiano. Lungo un percorso di scoperta con esercizi e case studies si esplora l'integrazione possibile tra gratitudine e mindfulness. L'atteggiamento grato e la pratica meditativa possono, se coltivate, trasformare in meglio la vita delle persone e delle comunit&
