Mahavagga, Khandaka 1, Chapter 3

1. Then the Blessed One, at the end of those seven days, arose from that state of meditation, and went from the foot of the Ajapāla banyan tree to the Mucalinda tree. And when he had reached it, he sat cross-legged at the foot of the Mucalinda tree uninterruptedly during seven days, enjoying the bliss of emancipation.

2. At that time a great cloud appeared out of season, rainy weather which lasted seven days, cold weather, storms, and darkness. And the Nāga (or Serpent) king Mucalinda came out from his abode, and seven times encircled the body of the Blessed One with his windings, and kept extending his large hood over the Blessed One's head, thinking to himself: 'May no coldness (touch) the Blessed One! May no heat (touch) the Blessed One! May no vexation by gadflies and gnats, by storms and sunheat and reptiles (touch) the Blessed One!'

3. And at the end of those seven days, when the Nāga king Mucalinda saw the open, cloudless sky, he loosened his windings from the body of the Blessed One, made his own appearance disappear, created the appearance of a youth, and stationed himself in front of the Blessed One, raising his clasped hands, and paying reverence to the Blessed One.

4. And the Blessed One, perceiving that, on this occasion, pronounced this solemn utterance: 'Happy is the solitude of him who is full of joy, who has learnt the Truth, who sees (the Truth). Happy is freedom from malice in this world, (self-)restraint towards all beings that have life. Happy is freedom from lust in this world, getting beyond all desires; the putting away of that pride which comes from the thought "I am!" This truly is the highest happiness!'

Here ends the account of what passed under the Mucalinda tree.
