坐禪三昧經 2.7

2.7

心靜默然，本所不得，今得此喜。是時心觀，以喜為患，如上覺觀，行無喜法，乃離喜地，得賢聖所說樂，一心諦知念護得入三禪。

The mind is serene and silent; having never attained it before, he now attains this joy. At that time, the mind contemplates and considers joy to be an affliction, just like initial and sustained thought above; practicing the dharma of joylessness, he then leaves the plane of joy, attains the bliss spoken of by the noble ones, and with one-pointedness of mind, careful understanding, mindfulness, and equanimity, attains entry into the third dhyāna.
