觀無量壽佛經義疏 3.213

3.213

"‘Having heard, they believe and understand, and give rise to the mind of supreme enlightenment. After ten small kalpas have elapsed, they are fully endowed with the hundred gates of luminous dharmas and attain entry into the first bhūmi.’" In these three lower grades, upon being born there and hearing the Dharma, they all give rise to the great aspiration. The three middle grades above only explained small fruits, because they had previously given rise to the great aspiration, so it was not explained there. The "hundred gates of luminous dharmas" has the same meaning as explained previously. Third, the conclusion.
