大般涅槃經義記 3.307

3.307

第五句中，「凡人」喻於凡夫、二乘、始行菩薩，顯性行微名為「薄福」，想心推求故說「钁斲」，勤求不見說言「加功困苦不得」。

In the fifth clause, "ordinary persons" is a metaphor for ordinary beings, practitioners of the two vehicles, and bodhisattvas of initial practice; that their practice revealing the nature is slight is called "meager merit"; seeking by means of conceptualizing thoughts is therefore spoken of as "hoeing and chopping"; striving to seek but not seeing is spoken of as "applying effort in weariness and hardship without obtaining it."
