Venerable Ekagatta discusses sutta 12.23 from the Samyutta Nikaya: Upanisa Sutta - Proximate Cause. 

Read SN12.23 here on Sutta Central.

"The ending of defilements comes only when the truth is seen. But seeing the truth comes about due to a vital condition. In this way, twelve factors leading to freedom are united with the twelve factors leading to suffering", Sutta Central.
