Four Stages of Arhat

1. The Buddha said, "Those who, taking leave of their families and adopting the life of renunciation, understand the mind, reach the source, and comprehend the immaterial, are called Sramanas. Those who observe the two hundred and fifty precepts of morality, who are pure and spotless in their behaviours, and who exert themselves for the attainment of the stages of progress, are called Arhats. The Arhat is able to fly through space and assume different forms; his life is eternal, and there are times when he causes heaven and earth to quake.

Below them is the Anagamin who, at the end of a long life, ascend in spirit to the nineteenth heaven and obtains Arhatship.

Next come the Skridagamin who ascends to the heavens (after his death), comes back to the earth once more, and then attains Arhatship.

Then come the Srotaapanna who cannot become Arhat until he has passed seven more rounds of birth and death. By the severance of the passions is meant that like the limbs severed they are never again made use of." ~ The Sayings of the Buddha in Forty-Two Sections

NOTE: In ascending order, they are

- the stage of the stream-winner (Skt. srotaapanna ),
- the stage of the once-returner (sakridagamin) ,
- the stage of the non-returner (anagamin), and
- the stage of arhat.
