Definitions

Mipham Rinpoche states:

Distraction [vikṣepa] belongs to the categories of the three poisons. It is the mental motion or wandering towards an object which causes the inability to remain one-pointedly on a virtuous objective. It can be defined as distraction towards the outer, towards the inner, and towards status.

The Abhidharma-samuccaya states:

What is desultoriness? It is to be it scatter-brain and belongs to the categories of passion-lust (raga), aversion-hatred (dvesha), and bewilderment-erring (moha). Its function is to obstruct one from becoming free of passion-lust (Raga).

Alexander Berzin explains:

Mental wandering (rnam-par g.yeng-ba) is a part of longing desire (Raga), hostility (Dvesha), or naivety (Moha). It is the subsidiary awareness that, due to any of the poisonous emotions, causes our mind to be distracted from its object of focus. If we are distracted due to longing desire, the object of our desire need not be something we are already familiar with, as in the case of flightiness of mind.
