Samaññaphala Sutta - The Fruits of the Contemplative Life
Household life is confining, a dusty path. The life gone forth is like the open air. It is not easy living at home to practice the holy life totally perfect, totally pure, like a polished shell.
...Endowed with this noble restraint over the sense faculties, he is inwardly sensitive to the pleasure of being blameless.
...With his mind thus concentrated, purified, and bright, unblemished, free from defects, pliant, malleable, steady, and attained to imperturbability, he directs and inclines it to creating a mind-made body. From this body he creates another body, endowed with form, made of the mind, complete in all its parts, not inferior in its faculties. Just as if a man were to draw a reed from its sheath. The thought would occur to him: 'This is the sheath, this is the reed. The sheath is one thing, the reed another, but the reed has been drawn out from the sheath.' Or as if a man were to draw a sword from its scabbard. The thought would occur to him: 'This is the sword, this is the scabbard. The sword is one thing, the scabbard another, but the sword has been drawn out from the scabbard.' Or as if a man were to pull a snake out from its slough. The thought would occur to him: 'This is the snake, this is the slough. The snake is one thing, the slough another, but the snake has been pulled out from the slough.' In the same way — with his mind thus concentrated, purified, and bright, unblemished, free from defects, pliant, malleable, steady, and attained to imperturbability, the monk directs and inclines it to creating a mind-made body. From this body he creates another body, endowed with form, made of the mind, complete in all its parts, not inferior in its faculties.

Brahmajala Sutta - The All-embracing Net of Views - Verse 36
Having understood as they really are the origin and the passing away of feelings, their satisfaction, their unsatisfactoriness, and the escape from them, the Tathāgata, bhikkhus, is emancipated through non-clinging.

Bhikkhus! Since the Tathagata rightly knows the arising of feeling (vedana) and its cause, the cessation of feeling and its cause, its pleasantness, its faults, and freedom from attachment to it, he becomes liberated without any clinging, (i.e., he realizes Nibbana).
