阿彌陀經通贊疏 3.3

3.3

贊曰：第二說多因也。善男子者，梵云烏波索迦，此云近事男，索者男聲也，堅持五戒堪可親近承事比丘僧故。善女人者，烏波斯迦，斯者是女聲也，亦持五戒堪可承事比丘尼故。西天分男女二聲故。聞說阿彌陀佛者，謂於善友處聞此阿彌陀教中往生之事，或自尋覽。執持佛名號一日乃至七日一心者，更無間隔，故名曰一心。不亂者，專注無散也。

The commentary states: The second [section] explains the many causes. 'Good man' in Sanskrit is upāsaka, rendered here as 'near-serving man'; -aka indicates masculine gender, because by firmly upholding the five precepts he is qualified to draw near and serve the assembly of bhikṣus. 'Good woman' is upāsikā; -ikā indicates feminine gender, because she also upholds the five precepts and is qualified to serve the bhikṣuṇīs. This is because in the Western region [Sanskrit] distinguishes masculine and feminine genders. 'Hearing spoken of Amitābha Buddha' means hearing about the matter of rebirth in the teaching of this Amitābha from a good spiritual friend, or investigating it oneself. 'Holding fast to the Buddha's name for one day up to seven days whole-heartedly': with no further interruption, it is therefore called 'whole-heartedly'. 'Without distraction' means concentrated and unscattered.
