Commentary

The syntax of my translation is different from previous translations given I am very mindful of the gerund "prāpya", the accusative case of "śubhāśubham", and the connection of "tasya" with "prajñā pratiṣṭhitā".  My translation is most like the Laurie L. Patton translation. This is the translation I rely on the most when I am confused about a particular verse.
