In a teaching on the qualities of the 10 powers of the Buddha, Khensur Rinpoche Jampa Tegchok stated:
In the context of the third power [the power of exalted knowledge of the varieties of inclinations], there are two different meanings of desire. The positive type is e.g. having strong aspiration towards emptiness, which is not negative, like attachment. When desire is negative, it acts upon causes and conditions that perpetuate samsara, whereas desire towards emptiness actually eliminates samsara,
and that is positive. In the process of thinking about and aspiring to emptiness, it is impossible for [afflicted] attachment to arise; that is actually what eliminates desire.
