<please remember that I am a terrible sinner and know nothing. The only advice I give is to talk to your priest about this>
Sure thing - just over here
Yeah, let's talk here.
The intellect is not an evil or bad thing. it is simply for a different purpose. Since we have cultivated the intellect and in our society we hold it in high regard it is far easier for us to use it. We are heavily tied to the intellect and it is VERY easy for us to be derailed visual images or concepts.
This topic for me is so closely tied to the logismoi that I think it would be good to talk about them as well as the nature and development of a sin as well.
Sin starts as a movement. A stirring up of the passions. A demon for example will stir up the passions inside you and will use them to create an image. Let's say this image is a you shoplifting a prada purse. Normally this is not something that you would think of or even consider right? (RIGHT?>!>!> just kidding...

) so... there you are and you have this nasty image in your head and for some reason it is just there.
So you are at this point being presented with an idea - an image. You have not committed a sin as of yet you are simply being tempted. This is phase zero.
Now comes the choice - you can either ignore the image, fight against it or you can entertain it.
If you decide to entertain this image then it will start to try to bring your will into allignment with it. You still have not sinned but this is really your last chance to escape without sinning. You again have choices - you can choose to ignore the idea, you can fight against it actively or you can go with it.
Here is phase one.
So. Your will has now come in line with this image. You have now sinned. You have aligned yourself with evil. Now you again are presented with options. You can repent - that is you can change your mind about this, you can forget about it or you can proceed to...
Phase two.
Planning. You are now acively sinning. You now have made the image your own and brought your will into alignment with it. You now go into planning to actually commit the physical action. Again - you can choose to repent or you can then go on to execution.
At this point you are already in deep yogurt. You have sinned and you are actively being damaged. It does not matter if somethijng prevents you from stealing the bag - you have sinned and you have damaged yourself for the future. Again the decision comes - Stop now or go on to...
Phase three - execution.
You steal the bag and run out of the store and now you have this bag.
This is it - you have gone through with the full execution of the sin.
At this point you have been damaged and you are in deep yogurt and you ahve been in a cycle of ever growing sin since moving to phase 1.
We can see that all of this started with a passion. The demon used this passion inside you to bring forth this image - this logismoi. This was the point where the intellect got dragged off and hogtied because we are focused on what is happening in our head.
It s interesting to note that you can go from phase 0 to phase 3 in about as much time as it takes for light to travel 1cm. Still the phases happen in sequence. Passion stirred, image/thought/logismoi presented - our will comes into alignment, planning and then execution.
So.... how is it that we can stop this? The best thing is to become totally and completely dead to the world - the passions. That unfortunately is a gift that can take lifetimes to aquire and I certainly do not have it. So... what should some passionate soul like me do?
You go to the source. You watch the heart and you observe any movements. When you fail to watch the heart you get presented with images. BAH!
So.. now you have this iamge. What do you do? There are only so many options and if the thing turns out to be bad then we are in for a bad ride! We can fight against them but we have no strength of our own and a demon will simlly use our anger at the original image to lead us into some other sin. The best thing to do in the majority of cases is to ignore all images that come into your head. If we fail to catch them at the heart before they can be stirred up then we have to ignore them.
This is why we strive to ignore ALL mental images all the time - not only in prayer but also in daily life.
