瑜伽師地論略纂 7.29

7.29

'Sentient beings who fear extensive activity and are indolent' refers to those who take pleasure in hearing the concise and fear extensive cultivation of the trainings. Although there are the myriad practices of the six perfections, only the three trainings are spoken of, because the designation of the three trainings subsumes all practices; this is not an explicit statement, and is therefore called an intentional meaning.
