If our Observing Attention (OA) is inexperienced in the art of watchfulness it at once begins to entertain whatever impassioned fantasy appears in it, and plies it with illicit questions and responds to it illicitly. Then our own thoughts are conjoined to the demonic fantasy, which waxes and burgeons until it appears lovely and delectable to the welcoming and despoiled intellect. The OA then is deceived in much the same way as lambs when a stray dog comes into the field in which they happen to be: in their innocence they often run towards the dog as though it were their mother, and their only profit in coming near it is that they pick up something of its stench and foulness. In the same way our thoughts run ignorantly after demonic fantasies that appear in our OA and, as one said, the two join together and one can see them plotting to destroy the city of Troy like Agamemnon and Menelaus. For they plot together the course of action they must take in order to bring about, in practice and by means of the body, that purpose which the NOT-i's have persuaded them is sweet and delectable. In this way is sin: and hence the need to bring out into the open what is in our hearts.
