大般涅槃經義記 5.17

5.17

In the second section, there are four distinct clauses: first, contemplating that household life has many faults: the statement 'cramped like a prison' clarifies that it involves suffering, and 'afflictions arise from it' reveals that it involves evil; second, contemplating that renunciation has many benefits: 'spacious like the open sky' reverses the previous first clause to clarify that it involves joy, and 'good dharmas increase because of it' reverses the subsequent clause to clarify that it involves goodness; third, clarifying that household life offers no benefit to oneself: 'one cannot purely cultivate brahmacaryā to the end of one's life'; fourth, from 'I should now...' onward, directly resolving to seek renunciation.
