Jhanas
Once-returner
Second Jhana
The second rank refers to those who have attained the first stage, that of the stream-winner (Skt srota-apanna ), or one who has entered the metaphorical river leading to nirvana; and to those the second stage, that of the once-returner (sakridagamin), or one who must undergo only one more rebirth in the human world before entering nibbana.
