觀念阿彌陀佛相海三昧功德法門 1.12

1.12

如是上下依前十六遍觀，然後住心向眉間白毫，極須捉心令正，更不得雜亂，即失定心，三昧難成。應知。是名觀佛三昧觀法。一切時中常迴生淨土，但依觀經十三觀安心，必得不疑。

In this way, contemplate from top to bottom through the preceding sixteen times, and then keep the mind focused upon the ūrṇā between the eyebrows. One must make the utmost effort to keep the mind upright, never allowing it to become mixed or scattered; otherwise one will lose the concentrated mind, and the samādhi will be difficult to accomplish. You should know this. This is called the contemplation method of the buddhadarśana-samādhi. At all times, constantly dedicate [merit toward] rebirth in the Pure Land. Just settle your mind according to the thirteen contemplations of the Guan jing, and you will certainly attain it without doubt.
