Lets use the example of over attachment to illustrate the Twelve Nidanas of dependent origination.
1. Ignorance (avijja): The person lacks understanding of the impermanent nature of all phenomena and the causes of their suffering.
2. Mental formations (sankhara): Due to ignorance, the person forms habitual patterns of attachment and craving towards certain people, objects, or situations.
3. Consciousness (viññana): The persons consciousness is conditioned by these mental formations, making them prone to experiencing and pursuing attachment.
4. Name and form (nama-rupa): The persons body and mind manifest in a way that is susceptible to attachment, leading to the formation of a separate self-identity.
5. The six sense bases (salayatana): The persons sense organs interact with the external world, including objects and people.
6. Contact (phassa): The person encounters objects, people or situations that trigger their attachment, usually leading to pleasant feelings.
7. Feeling (vedana): The person experiences a pleasant feeling as a result of contact with the object, person, or situation.
8. Craving (tanha): The person develops a strong desire to cling to and possess the object of attachment.
9. Clinging (upadana): The persons attachment and association with the object or person become intensified, leading to further entanglement and clinging.
10. Becoming (bhava): This clinging to attachment reinforces the persons habitual patterns and karmic tendencies, leading to the perpetuation of attachment and suffering.
11. Birth (jati): Attachment manifests itself in the persons ongoing desires and affections towards the object or person, which reinforce the mental formations and karmic consequences.
12. Old age and death (jara-marana): Unaddressed attachment can lead to physical, mental, and emotional suffering, and perpetuate negative karmic consequences in future lives.
In this example, we can see how the Twelve Nidanas apply to the arising and perpetuation of over attachment. By recognizing and understanding the interdependence of the Twelve Links, a person can cultivate mindfulness and work towards recognizing the impermanent nature of all phenomena, ultimately leading to the breaking of the cycle of suffering and reaching a state of true liberation.

How to break cycle at each point:

How to break the cycle of over-attachment at each point in the Twelve Nidanas:

1. Ignorance (avijja): Breaking the cycle at the point of ignorance involves developing an understanding of the impermanent nature of all phenomena and the causes of suffering. This can be achieved through study, reflection, and meditation on the teachings of the Buddha, as well as through seeking guidance from experienced teachers.

2. Mental formations (sankhara): To break the cycle at this point, it is important to become aware of the habitual patterns of attachment and craving that arise from our mental formations. By practicing mindfulness and investigating the underlying causes of our desires and aversions, we can begin to transform our responses and cultivate more wholesome mental formations.

3. Consciousness (viññana): Breaking the cycle at the point of consciousness involves developing a more mindful and discerning relationship with our senses. By recognizing the impermanent and conditioned nature of sensory experiences, we can begin to let go of attachment and cultivate a more equanimous relationship with the world around us.

4. Name and form (nama-rupa): To break the cycle at this point, it is important to recognize the illusory nature of the self-identity that arises from our name and form. By cultivating awareness of the changing nature of our thoughts, emotions, and physical experiences, we can begin to let go of the need to cling to a fixed sense of self.

5. The six sense bases (salayatana): Breaking the cycle at the point of the six sense bases involves practicing restraint and non-attachment towards sensory experiences. By cultivating awareness of the fleeting nature of sensory experiences, we can begin to let go of attachment and become more mindful of the present moment.

6. Contact (phassa): To break the cycle at this point, it is important to cultivate mindfulness of the habits of mind that arise from contact with pleasurable objects. By recognizing the ways in which we create a sense of self through our attachments, we can begin to let go of attachment and cultivate a more open and receptive attitude towards the world around us.

7. Feeling (vedana): Breaking the cycle at the point of feeling involves developing a more discerning and balanced relationship with our emotions. By recognizing the impermanent nature of our feelings and becoming more mindful of the causes and conditions that give rise to them, we can begin to let go of attachment and cultivate a more resilient and balanced emotional state.

8. Craving (tanha): To break the cycle at this point, it is important to recognize the ways in which craving for pleasurable experiences or objects leads to further suffering. By cultivating contentment and gratitude for what we already have, we can begin to let go of attachment and craving and cultivate a more peaceful and joyful state of mind.

9. Clinging (upadana): Breaking the cycle at the point of clinging involves recognizing the ways in which attachment leads to a sense of constriction and suffering. By practicing non-attachment and letting go of our need to control or possess objects and experiences, we can begin to cultivate a more open and expansive mindset.

10. Becoming (bhava): To break the cycle at this point, it is important to recognize the ways in which our habitual patterns of attachment lead to the perpetuation of suffering. By cultivating a more mindful and discerning approach to our actions and intentions, we can begin to let go of attachment and create more positive karmic consequences.

11. Birth (jati): Breaking the cycle at the point of birth involves cultivating awareness of the link between our habitual patterns of attachment and the ongoing cycle of birth and rebirth. By recognizing the ways in which our actions contribute to our own suffering, we can begin to let go of attachment and cultivate a more compassionate and wise perspective on life.

12. Old age and death (jara-marana): Breaking the cycle at the point of old age and death involves recognizing the inevitability of impermanence and cultivating acceptance of our own mortality. By recognizing the ways in which our attachment to the body and to sensory experiences leads to suffering, we can begin to let go of attachment and cultivate a more peaceful and equanimous relationship with the world around us.
