This is a comprehensive group which contains a number of volitional factors. In Abidhamma 50 types of mental formations are mentioned. Of these, the most important is volition or will. This is the mental factor which arouses us to act by way of body or speech. Mental formations also include all different desires and emotions, including the wholesome and unwholesome roots. These are the basic psychological roots of unwholesome actions: greed hatred and delusion, and the basic roots of wholesome actions: generosity, loving kindness and wisdom.
