Ajahn Vayama uses the Buddhist teaching of the Iddhipadas (Roads to Success), especially the quality of aditthana (determination) which is a wholesome desire to overcome the unwholesome desires of sensual craving which lead to suffering. In this way Ajahn Vayama outlines what type of desire is useful in Buddhist practice, and what desire is an obstacle and burden.
