What is the central claim in Buddhism?

In Buddhist phenomenology and soteriology, the skandhas (Sanskrit) or khandhas (Pāḷi) are the five functions or aspects that constitute the sentient being. In English, these five aspects are known as the five aggregates. The five aggregates are: material form, feelings, perception, volition (sometimes translated as mental formations), and sensory consciousness. Considering that the five aggregates continuously arise and cease within our moment-to-moment experience, the Buddha teaches that nothing among them is really "I" or "mine."

In the Theravada tradition, suffering arises when one identifies with or clings to an aggregate. Suffering is extinguished by relinquishing attachments to aggregates.

• Has it? If not, why not? If so, where and what are the results?
