[346] "Furthermore, Udāyi, with the abandoning of pleasure … a bhikkhu enters and dwells in the fourth jhāna (catutthaṃ jhānaṃ). He sits pervading this very body with a mind that is pure and bright; there is no part of his entire body that is unpervaded by the pure, bright mind. Just as, Udāyi, a man might sit having covered his head with a white cloth, and there would be no part of his entire body untouched by the white cloth—even so, Udāyi, a bhikkhu sits pervading this very body with a mind that is pure and bright; there is no part of his entire body that is unpervaded by the pure, bright mind.
And therein many of my disciples dwell having attained the consummation and perfection of direct knowledge (abhiññā)."
