大方廣佛華嚴經疏 6.40

6.40

三一念等者，修福德因、感依正果，福之力也。雖多人多劫，所感念劫融之頓現。此於時劫得解脫也。

In the third, "in a single thought," and so on, means cultivating the causes of merit and experiencing the primary and secondary results, which is the power of merit. Although involving many people and many kalpas, the results experienced merge the thoughts and kalpas to appear instantaneously. This attains liberation from [the obstacle of] time and kalpas.
