Little Catechism of Prayer

Meditation and colloquy in the Carmelite tradition. To quote:

There are some differences among Carmelite authors in the manner of presenting meditation, but all are in accord as to the essentials.  Some speak of it without distinguishing its various elements.  Others distinguish the loving colloquy  from the meditative reflection which leads to it, and call this colloquy contemplation.  Others subdivide meditation itself into the elements of representation and reflection.  Those who do not specifically treat of these various elements still make some allusion to them.  We may therefore assert that the majority of our Carmelite authors distinguish three elements in meditation:
1. Representation- the work of the imagination.
2. Reflection- the work of the intellect
3.  Colloquy- the work of the will.
