Lets use the example of a person experiencing a lack of boundaries to illustrate the Twelve Nidanas of dependent origination.
1. Ignorance (avijja): The person lacks understanding of the importance of healthy boundaries or the true nature of reality as interdependent and interconnected.
2. Mental formations (sankhara): Due to ignorance, the person has formed habitual patterns of not setting boundaries and habitually prioritizing the needs of others at the expense of their own well-being.
3. Consciousness (viññana): The persons consciousness is conditioned by these mental formations, resulting in them remaining unaware of the need for boundaries.
4. Name and form (nama-rupa): The persons body and mind (psychophysical constituents) manifest in a way that is unclear about their own needs and personal space.
5. The six sense bases (salayatana): The persons sense organs (sight, hearing, smell, taste, touch, and mind) interact with the external world.
6. Contact (phassa): The person encounters situations where their boundaries are crossed, such as someone taking advantage of them or disrespecting their individual rights.
7. Feeling (vedana): The person experiences a mix of unpleasant feelings such as guilt, shame, and anger as a result of the crossed boundaries.
8. Craving (tanha): The person continues to prioritize the feelings and needs of others, developing a craving for approval and validation.
9. Clinging (upadana): The persons attachment to seeking approval and validation makes it difficult for them to establish and maintain healthy boundaries.
10. Becoming (bhava): The persons clinging reinforces their patterns and karmic tendencies, perpetuating the cycle of boundarylessness.
11. Birth (jati): The person is born into a cycle where they habitually deny themselves their needs and desires in life, focusing instead on fulfilling the needs of others.
12. Old age and death (jara-marana): This cycle can lead to physical, mental, and emotional suffering such as burnout and lack of self-worth, perpetuating negative consequences even in future situations or future lives.
In this example, we can see how the Twelve Nidanas apply to the arising and perpetuation of a lack of boundaries. By understanding the dependent origination of boundarylessness and recognizing the interdependence of the Twelve Links, a person can cultivate mindfulness and work towards setting healthy boundaries, ultimately leading to greater self-awareness, balance, and a reduction in suffering.

How to break cycle at each point:

To break the cycle of dependent origination and address the issue of lack of boundaries, one can apply the following strategies at each point of the Twelve Nidanas:

1. Ignorance (avijja): Building awareness of the importance of healthy boundaries and the interdependence of all phenomena through reading, learning, and seeking out teachings on Buddhist principles.
2. Mental formations (sankhara): Developing new habits and patterns of prioritizing ones own needs as well as the needs of others through meditation, self-reflection, and cultivating self-compassion.
3. Consciousness (viññana): Becoming more mindful of the need for healthy boundaries and recognizing when others may be crossing them through mindful introspection and self-awareness practices.
4. Name and form (nama-rupa): Cultivating a deeper understanding of ones own needs and personal space through introspection, self-reflection, and mindfulness practices that foster self-awareness.
5. The six sense bases (salayatana): Engaging in sensory experiences mindfully and setting healthy boundaries by saying no to situations that one knows is harmful to self.
6. Contact (phassa): Learning to recognize when boundaries are being crossed and taking action to set clear, healthy boundaries through assertiveness and communicating ones own needs with empathy.
7. Feeling (vedana): Developing a deeper understanding of ones own emotions and cultivating skills for managing emotions through mindfulness and insight practices.
8. Craving (tanha): Recognizing the craving for validation and approval, and developing a sense of self-worth that is not contingent on external factors through meditation, self-reflection, and self-compassion practices.
9. Clinging (upadana): Establishing and maintaining healthy boundaries by building emotional resilience and avoiding patterns that reinforce the cycle of craving and clinging.
10. Becoming (bhava): Fostering a sense of balance by practicing self-care and self- compassion, and by recognizing and transforming patterns of unhealthy behavior that perpetuate suffering.
11. Birth (jati): Developing a balanced and fulfilling lifestyle by periodically checking on the balance between own needs and the needs of others to maintain healthy boundaries.
12. Old age and death (jara-marana): Avoiding burnout and emotional exhaustion by enforcing healthy boundaries in work and personal life thereby preserving physical, mental, and emotional well-being.

In summary, one can break the cycle of dependent origination at each point by cultivating mindfulness, self-awareness, and self-compassion. By doing so, they create new patterns of behavior and attitudes that lead to greater balance in life and healthy boundaries between oneself and others.
