What Buddha's techniques I can use to uproot deep craving for a woman's love? I am not geographically close to this woman, nor do I ever talk to her, she's just my teenage obsession that lingers on my mind. I am too much attached to my perceptions about how she is, and because I cannot be near to her geography nor can I talk to her because of a past issue, I feel emptiness inside me. I feel lonely and I crave presence. I satisfying this craving my visualisations and fantasies. How can I get rid of this from deep inside. I have gotten rid of this from conscious thinking, but deep inside it still exists. Currently I am practicing 32 Body part meditation, Vipassana and Anapana Meditation. Can you suggest any specific exercise that would help me with this particular issue?
First, know that you are not alone. Nearly every person experiences something like this to varying degrees and intensity at some points in time.

Second, realize that this has nothing to do with her. This is about your own internal emotions and desires and fantasies. You are experiencing self-cherishing. In all of these obsessions and fantasies it is not an external person who is the focus of your thoughts - although I am sure it absolutely feels like it - it is actually yourself that is the focus.

Third, to really get a good sense for this ask yourself whose wellbeing are you truly concerned with when these thoughts come up? Is it this far away person who is probably quite different from your internal idea of her? Are you concerned with her day-to-day well being? Or is it yourself?

Fourth, realize that this self-cherishing is unsatisfactory and is leading you to suffering. You already do recognize this to some extent and that is why you are asking this question. Rejoice that you have recognized it! Now deepen it. It is you that is suffering with this.

Fifth, let it be. These negative self-cherishing emotions arise based on countless karma and habits that you have been acquiring for a very very very long time. You can’t just make them or force them to go away. So let them be and don’t give them added energy. When they come up try and recognize them for what they are: self-cherishing thoughts that lead to suffering.

Sixth, practice other-cherishing. When you are not beset by these thoughts, try to establish the habit of truly caring for and working toward and wishing for the well-being of others. The only way to truly rid yourself of those self-cherishing thoughts is to create the habit of other-cherishing and gradually replace one habit with another. This will take time.

Seventh, be honest with yourself and the whole situation. You have established a very bad habit that is hurting and it will take time and effort to replace it. Be gentle with yourself and cherish others.
