三者、念。念世間為欺誑可賤，念禪定為尊重可貴。若得禪定，即能具足發諸無漏智，一切神通道力，成等正覺，廣度眾生，是為可貴，故名為念。

The third is mindfulness (smṛti). Being mindful that the world is deceptive and contemptible, and being mindful that dhyāna-concentration is venerable and precious. If one attains dhyāna-concentration, one will be able to fully develop all untainted wisdom and all powers of spiritual penetration and the path, realize equal and perfect enlightenment, and broadly deliver sentient beings. This is precious, and therefore it is called mindfulness.
