法華經義記 5.55

5.55

問者又言：「若言失者，今云何還生耶？」解釋者言：「此失非是永斷善根成一闡提，只言煩惱五濁既多，于時解心不現前，名之為失。夫善生必以信心為本，于時雖失大解，由有信心，於五戒十善教中修行，能令大乘智願善根不斷，是故『我昔教汝志願佛道。汝今悉忘。我今還欲令汝憶念本願所行道。』故若言永斷者，云何言憶也？」

The questioner further asks: 'If you say it was lost, how does it arise again now?' The commentator explains: 'This loss is not a permanent severing of wholesome roots to become an icchantika. It only means that because afflictions and the five turbidities were numerous, at that time the mind of understanding was not manifest; this is called "loss". Now, the arising of wholesome [qualities] must take the mind of faith as its foundation; at that time, although they lost the great understanding, because they still had the mind of faith and cultivated within the teachings of the five precepts and ten virtues, they were able to keep the wholesome roots of the Great Vehicle's wisdom and vows from being severed. For this reason [the Buddha says]: "In the past I taught you to resolve upon and aspire to the Buddha-path. Now you have completely forgotten it. I now wish again to cause you to recollect the path practiced according to your original vow." Therefore, if one says it was permanently severed, how could he speak of recollecting it?'
