After emerging from seven days of `samādhi` (concentration), the Bhagavā spent another seven days at the Mucalinda tree experiencing the bliss of `vimutti` (liberation). During this period, an unseasonal storm arose, prompting Mucalinda, the nāga king, to protect the Bhagavā by coiling around his body and spreading a hood over his head for seven days. Once the storm cleared, Mucalinda transformed into a young man and paid homage. In response, the Bhagavā uttered an `udāna` (inspired utterance) extolling the happiness of `viveka` (solitude) for the content who have heard the Dhamma, `abyāpajja` (non-affliction) towards beings, `virāgatā` (dispassion) from sensual pleasures, and identifying the dispelling of `asmimāna` (the conceit 'I am') as the supreme happiness.
