說無垢稱經疏 2.142

2.142

贊曰：此之一頌，群生賚斯得度生死。以斯妙法牒上法輪，得果圓滿更無所畏，已超生死更無所畏，故得涅槃體常安寂，故說佛是能度生死之大醫王。我今稽首無邊德，舊云「一受不退常寂然」，得本寂已更不退轉故常寂然，便闕無畏無怖義。

Commentary: This one verse explains that sentient beings, having received this, are able to cross over saṃsāra. 'By means of this wondrous Dharma' resumes the above wheel of the Dharma; having attained the culmination of the fruit, he has no further fear; having transcended saṃsāra, he has no further fear; therefore he attains Nirvāṇa whose essence is ever peaceful and tranquil, and so it is said that the Buddha is the great king of physicians who is able to cross sentient beings over saṃsāra. 'I now bow my head to the ocean of boundless merit.' The older reading says: 'Once received, non-retrogressing, ever tranquil'—having attained the original tranquility, he does not retrogress anymore and is therefore ever tranquil; this misses the meaning of fearlessness and dreadlessness.
