Dear Julia,
I will be honest with you - I haven't done the course as a 'whole'. At times is part of my 'morning coffee' along with Tarot, I-ching and the bulk of emails and tasks. And some times I save things that are remarkable for me - or things that gives me insights that feel like a real propulsion in growth/evolution.
I have recently discovered that iGoogle has a lot of gadgets that you can load on page...so I played with lots at first

however when it took ages for the page to load I had to censor the number. So I only have 4 and one of them is "A course in Miracles - Today's lesson" - I am not sure if you can see this but here is the link customised for me:
http://www.google.ca/ig?hl=en&source=iglkI was happy to discover this gadget as it comes really handy - now I don't have to make time or remember to go to today's lesson - and besides I always used to loose track.

Now back to the topic of this thread: lust.
Well, in my view, this urge, or feeling or emotion, is the strong, deep, burning desire I feel for the man I love. It comes from the spirit, not from the flesh. Without spiritual love, don’t feel ‘lust’ either.
The love without desire for lovemaking is not love of this earth. We are here Body, Mind and Soul, and it’s perfectly naturally to honour all needs and desires of these parts of the whole.
Life without passion is empty and boring (for me). Desire is a wonderful part of spiritual love, it completes it beautifully. “Lust” is the yearning to become one with the beloved. It’s not at all a ‘second hand’ emotion, but uplifting to heavens. Don’t think that it is an obstacle to spiritual ascension.
We live on earth now, in flesh. Afterlife we shall live in spiritual planes, and have the eternity to love spiritually.
Lust for me is something like a firecracker experience. It's got fire and boom but dissipates quickly and is gone as soon as the smoke clears. It can keep you searching for a bigger and better firecracker display.
I 'heard' lust is another idea of lack and so must over compensate in the idea based on fear of there not being enough.
In any case, to me lust is more of a negative aspect of love, if it can even be considered that. More or less a strong urge to have sex with someone for no other reason then the sex itself. Lust is one of the leading drives for rapists but as I said earlier that is just my point of view. Actual love is not lust.
A sensitive enough women can easily tell just by looking deep within the males eye whther or not his "come on" or "pick up line" is for the sake of being with her or just wanting to "hit that" for that night .
a person is driven purely by primal sexual desire for another person
I feel sure that "lust" is a primal reproductive animal instinct driven by hormones and the Ego, and not filtered through consciousness to any further extent than "fancying someone".
"Lust" is not attraction between two people even though it may bring two people together in order to satisfy their respective lust.
There is nothing intrinsically "wrong" with "lust" - it is a completely natural aspect of human nature.
but before a human can progress Spiritually they must overcome it.
And this is from the Dictionary.com

And going back to eternal questioning I wonder ...have we really answered?!?
How do you people see these matters?
You think it's true that in this lifetime the trick is to keep the soul as unpolluted as possible?
Do you find this harder then normal when you're dealing with sexual feelings and lust?
Do you separate love and lustful sex or is your sex always without exception related to love, even in fantasies?
I assume all this has consequences for the soul as well?
I admit to have lustful thoughts myself even though certain thoughts are unethical. I sometimes wonder why people get turned on by these thoughts.... is it a lack of love in their lives or doesn't that have anything to do with it? Perhaps love and lust should be in balance but is out of balance in lot's of people's minds?
In my opinion, the 'sex' subject is one of the most complex weird things that can seriously screw with my mind. What is unethical .... where do you draw the line...etc.
Dear Awakened Soul
From what you are telling us it seems that you are aware that you have sexual desires which translate in lustful dreams, and you are worried on how will that affect your life as a whole.
First please allow me to say (I am not sure how old you are but) is pretty remarkable that you are giving this matter such careful consideration. Hats off.
We have to have one fact clear from the start though.
1. Time comes when we have to take full responsibility of everything that happens or have in our lives, so what I am about to say is filtered through that. Sooner or later the responsible ones will fully accept everything they create.
2. Basically I suppose the idea is "what is the best dream to dream" when it comes to lust - which is your natural body impulse/nature - taking in account that there are others and they have their own dreams about how it should be.
As we remember that we are One - we have to keep in mind we are not alone.
You have a 'sexual desire' the Mind will start 'playing a movie' on how it should be, then you get carried on and build upon that.
Depending on how much emotional energy you put in it - I can assure you sooner or later it will come in your life. It won't happen overnight it may take a year or more… but eventually it will.
There is a big warning sign here though!!!! Your 'subconscious' picture or mental idea in its totality will come to be. Whatever you hold in there in its totality.
The irony of the thing goes along with "be careful with what you wish for" as when you dream your sexual dream you are not aware that you are totally overlooking other aspects of your ideal movie/story etc.. you think is assumed .. you think everything is in place and only you need to satisfy your 'at hand' urge which is your lustful thought at that moment.
The warning here is that the person that comes into your life will be a person with ‘other’ personality, trait aspects of her/his own – however !! it will fit perfectly your primarily ‘lustful desire’ that you put out in the Universe.
Or like Adrian hints – that person will match your vibration (again please keep in mind that your lustful fantasy, dream imagining etc.. is a very powerful vibration)
Because the original ‘lust, desire, passionate fantasy’ that little movie that you play where no-one can see

is a blueprint.
Due to inexperience/ignorance etc. unfortunately the 'ideal picture' of how that person should be ‘as a whole’ to match your needs or ‘other vibrations’ is not formed yet.
Is like you don’t even know what you need because is like a constant feed-back : “I think I know what I need but I will know for sure what I need when I have it and I see that IS what I need or is what I don’t “ kind of thing… and in the end is more like you know more what you don’t need rather than what really makes you blissfully happy.
That person however will show up – the one matching perfectly the primary vibration you cast in your energetic blueprint - and you will have your blissful moments, perhaps make house if you are like the most people (we are not talking here extremes lecherous thoughts) - so if you are a decent person you will marry or have a longer relationship with that person, then in time you will see on how time comes when you will feel as you are 'more trying to make it work' rather than having it ALL.

In other words as we grow older we become wiser and we start to see that there’s more to what makes an ideal relationship – a perfect medium to bring life and raise that life, a perfect life companion – etc.
I don’t believe there’s an ideal answer as in ‘do this’, ‘don’t do that’ etc. And if you look to guide yourself according solely to the morals that you hear and learn you will loose as nothing that comes from outside will make a whole life for yourself.
You are the only one that know what you need what makes you happy. Or, what your real needs are.
No matter what people say the vast majority they DO want to be with their ideal life partner. Someone who can match everything that you are: your sexual needs – in their totality because if you are a normal person you will want beauty to be part of that, your pace of growth – you want someone who has the same idea about personal growths and direction, your need for novelty and surprise, your need for being – as in genuinely feeling good with that person at any time, your need for being sensed – as in that person instinctively knowing what moves you or when you need your time outs and so on.
Next time when you are by yourself and the lust energy engulfs you

try to picture more details because you are creating a person, a mate eventually – you get it??
And that mate will come when you are ready and when she/he is ready (as in formed according to the both of you dreams).
Is not only that you have a lustful dream with some unidentified object of sexual desire. That person really exists out there – make no mistake it is, and will show up in your life!! In a month, a year or perhaps 10… nobody can tell how long it will take for the gestation period.
Now, what else you want how else you want that person to be?!?: i.e. you want children she needs to be a good mother …feel that!! Recall good images/feelings related to that..
You want someone to listen to you with compassion?!? Feel that with same intensity as your lustful desire;
You want someone that is good looking and smart and you are proud to have someone like that along your side?!? Feel that !! guide your feelings to be as intense as your lust at that moment
You want someone that can hold you when in need that is for you and with you no matter the life circumstances and the ‘hot’ studs parading in front of her she will still have the ‘hots’ for you and only for you – coz imagine all possibilities have an equal chance- well feel that make it part of your lustful dream.
And so on and son on …
I suppose this is called ‘responsible creation’. After all you do not exist only to satisfy your sexual needs – you have others, and as I said depending on how young you are you don’t even know what your needs are yet until you meet with what you don’t need or are smart enough to observe in others that which you don’t need for yourself.
In the end we come full circle to bible words: “Don’t do onto another that which you don’t want to be done onto yourself” or “Do onto another that which you want to be done to yourself”
When you think about it .. “lust” is what % of that which you want it done to yourself?? What 'else' you want it done to yourself?? (By that person you will satisfy your lust with ?!?)
Be the true image of your imagined lover.
In the end is all experience. We live… we learn.
Personally I can tell you that I dreamed a big faulty dream when it comes to total fulfilment as in 'happily ever after' kind of thing - just between the 2 of us the lust and desire eclipsed other essentials needed by myself as a whole being. (well dreamed...so far

...) Am I sorry for anything ?? NO!! It was exactly what I needed at that time and in retrospect I can see how it was all necessary for my evolution.
Now that I know I can dream a better dream.

And... I can tell you I am taking my sweet time with it.
Dear AS there more, so much more on this topic however this is all I have time for now. I hope any of it makes sense.
love
