There are 10 fetters or bonds that tie us to this samsaric world of existence. To become enlighten, we need to overcome or cut these fetters.

1. False belief in Self
2. Skeptical Doubt about the Dhamma
3. Attachment to Rites and Rituals, including norms, beliefs, concepts, names
4. Sense Desires
5. Ill Will
6. Attachment for existence in the Fine Material Planes
7. Attachment for existence in the Fine Immaterial Planes
8. Conceit
9. Restlessness
10. Ignorance

A Sotapana or Stream-Winner has eradicated the first 3 fetters of a false belief in Self, skeptical doubt and attachment to Rites and Rituals. He will have at most 7 more lifetimes before achieving enlightenment. Having eradicated the first 3 fetters, he will not fall back into the lower realms.

A Sakadagami or Once-Returner has further weaken but not totally eradicated Sense Desires and Ill Will. He will have only one more rebirth before attaining Nibbana.

An Anagami or Non-Returner has eradicated the first 5 fetters. He will be reborn in the Pure Abodes and from there attain Nibbana.

An Arahant has eradicated all the 10 fetters. He attains enlightenment in this very life.
