In this video started at 10m (I placed it at starting there), Bhikkhu Bodhi describes Stream Entry, Arhatship, and the Final Nibbana.
Let me know if it is something that is understood to you, or what frequencies your mind reacts on due to the seams of this video, especially the short bit about Entrance into Nibbana and Arhatship and Stream Entry, which I focused on studying while watching it starting at 10m.
