From Some of the Dharma, pp. 174-175:
Hit the makeless null. Whether or not individuality is destroyed now, it will be complelely destroyed in death. For all things that are made fade back to the unmade. What's all the return-vow hassle, but a final metaphysical clinging to eternal ego-life by Mahayana Thinkers. An intellectualized ego-attachment to taskhood. Hinayana, nay Ecclesiastes, is best.
