The Cullavagga (VI) gives this same story in greater detail and adds more incidents: After reciting the verse with which this discourse ends, the Buddha gives Anathapindika a step-by-step teaching, culminating in an explanation of the four noble truths. At the end of the teaching, Anathapindika attains stream-entry. He then returns home to Savatthi, purchases a grove from Prince Jeta at immense price, and establishes a monastery for the Buddha and the Sangha. There, according to the commentaries, the Buddha spent more rains retreats than at any other monastery.
When Anathapindika the householder had left the city, the light vanished and darkness appeared. Fear, terror, & horripilation arose, and because of that he wanted to turn back. Then Sivaka the yakkha-spirit, invisible, proclaimed:
A hundred elephants,
a hundred horses,
a hundred mule-drawn carts,
a hundred-thousand maidens
adorned with jewels & earrings
aren't worth one-sixteenth
of one step forward.Go forward, householder!
Go forward, householder!
Going forward is better for you,
not back!
The darkness then vanished for Anathapindika and the light appeared. The fear, terror, & horripilation he had felt subsided.
For a second time... a third time, the light vanished and darkness appeared. Fear, terror, & horripilation arose, and because of that Anathapindika wanted to turn back. Then for a third time, Sivaka the yakkha-spirit, invisible, proclaimed:
A hundred elephants,
a hundred horses,
a hundred mule-drawn carts,
a hundred-thousand maidens
adorned with jewels & earrings
aren't worth one-sixteenth
of one step forward.Go forward, householder!
Go forward, householder!
Going forward is better for you,
not back!
The darkness then vanished for Anathapindika and the light appeared. The fear, terror, & horripilation he had felt subsided.
So Anathapindika went to the Cool Grove. Now at that time, the Blessed One -- having gotten up as the night was ending -- was pacing back & forth in the open air. He saw Anathapindika the householder coming from afar. On seeing him, he got down from his meditation path and sat on a seat made ready. As he was sitting there he said to Anathapindika, "Come, Sudatta."
Then Anathapindika, [thinking,] "The Blessed One is calling me by my given name!" threw himself down right there at the Blessed One's feet and said to him, "Lord, I hope the Blessed One has slept in ease."
[The Buddha:]
Always, always,
he sleeps in ease:
the brahman totally unbound,
who doesn't adhere
to sensual pleasures,
who's without acquisitions
& cooled.Having cut all ties
& subdued fear in the heart,
calmed,
he sleeps in ease,
having reached peace
of awareness.
