瑜伽論記 12.153

12.153

義曰：以得無相故名多入無相，不樂進修，諸佛七勸令起無相觀，起無相觀已，自然如異熟任運勝進不待加行。

The explanation says: Because they have attained marklessness, they are said to enter marklessness frequently and take no pleasure in making further progress in practice. The Buddhas give the seven admonitions to make them arouse the contemplation of marklessness; having aroused the contemplation of marklessness, it naturally advances spontaneously like karmic maturation, without waiting for the application of effort.
