佛說觀佛三昧海經 3.59

3.59

At that time, the Tathāgata heard the words of the nuns and then smiled. A golden light issued from his mouth and circled the Buddha's silver body a full ten times. When this light appeared, the nuns saw the Buddha's purple-golden body and the thirty-two primary marks, with brilliance shining so brightly that it cannot be fully described. Having seen this, the nuns contemplated the white curl mark between his eyebrows coiling gracefully to the right. Having seen it, they rejoiced, and immediately attained the path of arhatship, being endowed with the three knowledges, the six supernormal powers, and the eight liberations.
