"Having abandoned these five hindrances — imperfections of awareness that weaken discernment — then, quite withdrawn from sensual pleasures, withdrawn from unskillful mental qualities, he enters and remains in the first jhana: rapture and pleasure born from withdrawal, accompanied by directed thought and evaluation.
"This, brahman, is called a footprint of the Tathagata, a scratch mark of the Tathagata, a tusk slash of the Tathagata, but a disciple of the noble ones would not yet come to the conclusion, 'The Blessed One is rightly self-awakened; the Dhamma is well-taught by the Blessed One; the Sangha of the Blessed One's disciples has practiced rightly.'
"Then, with the stilling of directed thoughts & evaluations, he enters and remains in the second jhana: rapture and pleasure born of composure, one-pointedness of awareness free from directed thought and evaluation — internal assurance.
"This, too, is called a footprint of the Tathagata, a scratch mark of the Tathagata, a tusk slash of the Tathagata, but a disciple of the noble ones would not yet come to the conclusion, 'The Blessed One is rightly self-awakened; the Dhamma is well-taught by the Blessed One; the Sangha of the Blessed One's disciples has practiced rightly.'
"Then, with the fading of rapture, he remains equanimous, mindful, & alert, and senses pleasure with the body. He enters & remains in the third jhana, of which the Noble Ones declare, 'Equanimous & mindful, he has a pleasant abiding.'
"This, too, is called a footprint of the Tathagata, a scratch mark of the Tathagata, a tusk slash of the Tathagata, but a disciple of the noble ones would not yet come to the conclusion, 'The Blessed One is rightly self-awakened; the Dhamma is well-taught by the Blessed One; the Sangha of the Blessed One's disciples has practiced rightly.'
"Then, with the abandoning of pleasure and pain — as with the earlier disappearance of elation and distress — he enters and remains in the fourth jhana: purity of equanimity and mindfulness, neither-pleasure-nor-pain.
"This, too, is called a footprint of the Tathagata, a scratch mark of the Tathagata, a tusk slash of the Tathagata, but a disciple of the noble ones would not yet come to the conclusion, 'The Blessed One is rightly self-awakened; the Dhamma is well-taught by the Blessed One; the Sangha of the Blessed One's disciples has practiced rightly.'
